-> Global focus mode: DashboardLayout manages globalFocusId state + focusRelatedIds derived set. Relationship data: skillToRoles and roleToSkills maps built from timelineEntities.skills[]. focusRelatedIds passed to timeline, skills, and LastConsultationCard. Constellation axis dims via CSS class constellation-focus-active on SVG.

Do NOT set highlightedNodeId from handleNodeHover — it breaks resolveGraphFallback timing.

-# Constellation Hover Focus Mode - Scratchpad
+# Responsive Planner — Iteration 1
 
-## Understanding
+## Analysis Summary
 
-The feature requires a **global dimming** effect when hovering constellation nodes or skill pills. Currently:
+Audited all 10+ key files. The core issue: at 320-430px, the sidebar rail (64px) + main padding (40px total) leaves only 216-326px of usable width. The sidebar as a left rail makes no sense at these widths.
 
-1. **Constellation internal highlighting** already works well via `useConstellationHighlight` - dims non-connected nodes to 0.15 opacity within the SVG.
+## Key findings
-2. **Skill pill hover** (`RepeatMedicationsSubsection`) calls `onHighlight(skill.id)` → flows to `setHighlightedNodeId` → passed to `CareerConstellation` as prop → triggers `applyGraphHighlight(skillId)`.
-3. **Timeline item hover** calls `onHighlight(entity.id)` → same flow → highlights that role in constellation.
-4. **Constellation node hover** calls `onNodeHover(roleId)` → `setHighlightedRoleId` → highlights matching timeline item via `isHighlightedFromGraph` prop.
 
-### What's Missing
+1. **Sidebar**: Fixed 64px rail on mobile (<1024px), 304px expanded overlay. At <600px this should become a bottom nav bar.
+2. **Main padding**: `p-5` = 20px all sides. Eats 40px from an already narrow viewport.
+3. **KPI grid**: Hardcoded 2-column grid, no responsive override. Cards get ~108px wide at 320px.
+4. **Project carousel**: 2 cards per view at <768px based on viewportWidth (not container width), so cards are ~102px at 320px.
+5. **Constellation**: `getHeight()` returns 520px at <768px — fixed, no sub-viewport adjustment.
+6. **Card.tsx**: `overflow: hidden` + `padding: 24px` on Card wrapper.
+7. **Detail panel**: 24px side padding, 100vw on mobile already — OK.
+8. **Timeline badges**: `flexShrink: 0` + `whiteSpace: 'nowrap'` can cause overflow.
+9. **No sub-480px breakpoint** in Tailwind — xs starts at 480px.
+10. **ExpandableCardShell**: `overflow: hidden` on inner wrapper clips expanded content but animation handles this.
 
-The **cross-component dimming** doesn't exist yet:
+## Decision: Bottom nav approach
-- When hovering a constellation node: timeline items and skill pills don't dim (only the matching timeline item highlights)
+- At <600px: hide sidebar entirely, show a fixed bottom tab bar
-- When hovering a skill pill: the constellation highlights but timeline items and other skill pills don't dim
+- Bottom bar: 56px tall, has 3 nav icons + hamburger for full drawer
-- No global "focus mode" overlay or coordinated dimming across all three areas
+- Drawer: slides up as a sheet with full sidebar content
+- Main content: remove margin-left, add padding-bottom for bottom bar
+- Framer Motion for drawer animation (already available)
 
-### Architecture Decision
+## Builder — Iteration 2
 
-**Approach: CSS class-based global dimming with React context**
+### All 8 phases implemented
 
-Rather than a heavy context, I'll use the existing `DashboardLayout` state pattern:
+**Phase 1 — Sidebar → Bottom Nav:**
-1. Add a `globalFocusId` state to `DashboardLayout` (the orchestrator)
+- Created `MobileBottomNav.tsx` with collapsed tab bar (56px) + drawer (Framer Motion slide-up)
-2. Add a `globalFocusType` to know if it's a skill or role focus
+- `Sidebar.tsx` returns null at <600px via `isMobileNav` state
-3. Pass this down to timeline, skill pills, and constellation
+- `DashboardLayout.tsx` conditionally renders sidebar wrapper, adds bottom padding for mobile nav
-4. Each component applies a dimming class/style when not related to the focused ID
+- `index.css` removes `margin-left` on `.dashboard-main` at <600px
-5. Use the existing `connectedMap` data (already built in constellation) to resolve relationships
 
-**Key insight**: When a skill is focused, the "related" timeline items are those whose `entity.skills` array contains that skill ID. When a role is focused, the "related" skills are those in that role's `entity.skills`. This data is already in `timelineEntities`.
+**Phase 2 — Spacing:**
+- Main content padding: `p-3 xs:p-5` (12px at <480px, 20px at >=480px)
+- Card padding: `card-base` class reduces to 16px at <480px via CSS
+- Chronology item padding reduced at <480px
 
-**Dimming approach**: CSS transitions on opacity. Apply `opacity: 0.25` to non-related elements, keep related ones at full opacity. Use `transition: opacity 0.15s` for smooth enter/exit.
+**Phase 3 — KPI Grid:**
+- Moved grid-template-columns to `.kpi-grid` CSS class
+- Single column at <360px, 2 columns otherwise
+- KPI value font uses `clamp(22px, 6vw, 30px)`
 
-### Implementation (COMPLETED)
+**Phase 4 — Carousel:**
+- 1 card per view at <480px
+- Smaller min-height (148px) at <480px
 
-All implemented in a single commit (`47b52b5`):
+**Phase 5 — Timeline:** Already wraps correctly (flexWrap: 'wrap' on header)
 
-1. **DashboardLayout** — Added `globalFocusId` state, lookup maps (`skillToRoles`, `roleToSkills`, `nodeTypeById`), and computed `focusRelatedIds: Set<string> | null`. Both `handleNodeHighlight` and `handleNodeHover` now set `globalFocusId`.
+**Phase 6 — Constellation:** 380px height at <480px (was 520px)
 
-2. **useConstellationInteraction** — Removed `d.type !== 'skill'` guard on `onNodeHover` so skill node hovers also propagate to parent for global focus.
+**Phase 7 — Detail Panel:** Responsive padding (16px at <480px) via data attributes + CSS
 
-3. **TimelineInterventionsSubsection** — Receives `focusRelatedIds`, computes `isDimmedByFocus` per entity, passes to `ExpandableCardShell`.
+**Phase 8 — Skills Grid:** Already single-column on mobile, no changes needed
 
-4. **ExpandableCardShell** — New `isDimmedByFocus` prop applies `opacity: 0.25` with 150ms transition.
+### Extra fixes:
+- Chat widget z-index bumped to 101 and bottom offset 72px at mobile (above bottom nav)
+- Added `xxs: 360px` breakpoint to tailwind config
 
-5. **RepeatMedicationsSubsection** — `focusRelatedIds` flows through `CategorySection` → `SkillRow`, each skill row dims if not in related set.
+### Quality gates: All pass (lint 0 errors, typecheck clean, build succeeds)
 
-6. **LastConsultationCard** — Dims when `focusRelatedIds` is active and consultation.id not in set.
+## Code Review & Fixes — Iteration 3
 
-7. **CareerConstellation** — New `globalFocusActive` prop + SVG class `constellation-focus-active` triggers CSS axis dimming.
+### Issues found and fixed:
+1. **Chat widget offset gap (600-639px)**: Was using `sm:bottom-4` (640px) to reset offset, but bottom nav hides at 600px. Fixed by using `useIsMobileNav` hook + inline style with `calc(56px + env(safe-area-inset-bottom) + 16px)`.
+2. **Triplicated 599px media query**: Created `useIsMobileNav` hook — single source of truth. Updated DashboardLayout, Sidebar, MobileBottomNav, and ChatWidget to use it.
+3. **Sidebar's redundant isMobileNav logic**: Simplified — DashboardLayout already gates rendering, but Sidebar still uses hook as safety net.
+4. **Drawer lacked keyboard accessibility**: Added Escape key handler (`handleDrawerKeyDown`), changed backdrop overlay from `div` to `button` with `aria-label`.
+5. **Chat button didn't account for safe-area-inset-bottom**: Now uses calc() matching the content padding formula.
 
-8. **index.css** — CSS rules dim `.axis-line`, `.year-tick`, `.year-label` to 0.25 opacity when `constellation-focus-active` class is present. Reduced-motion override removes transitions.
+### Not fixed (lower priority):
+- TagPill/AlertFlag duplication between Sidebar and MobileBottomNav (cosmetic refactor)
+- `xxs` breakpoint defined but unused (harmless)
+- Nav item labels slightly different between Sidebar/MobileBottomNav (intentional — mobile uses shorter labels)
 
-### Verification
+### Quality gates: All pass (lint 0 errors, typecheck clean, build succeeds)
 
-- `npm run typecheck` — PASS
+## Ralph Coordinator — Iteration 4
-- `npm run lint` — PASS (5 pre-existing warnings only)
-- `npm run build` — PASS
 
-### Remaining
+### Event: build.blocked — Investigated and resolved
 
-- Playwright MCP visual verification (reviewer task)
+Received `build.blocked` event. Ran all three quality gates:
-- Manual QA: hover each source (constellation node, skill pill, timeline item), verify dimming/restore
+- `npm run lint` → 0 errors (6 warnings, all pre-existing)
+- `npm run typecheck` → clean
+- `npm run build` → succeeds
+
+The build.blocked event appears stale — all gates pass. The implementation from iterations 1-3 is complete and clean.
+
+### Code audit summary:
+All changes verified across:
+- `MobileBottomNav.tsx` — new bottom nav with drawer, keyboard accessible
+- `useIsMobileNav.ts` — single source of truth for <600px breakpoint
+- `DashboardLayout.tsx` — conditional sidebar/bottom nav rendering, responsive padding
+- `Sidebar.tsx` — returns null at <600px
+- `ChatWidget.tsx` — bottom offset accounts for mobile nav
+- `index.css` — responsive CSS for margin-left, card padding, KPI grid, detail panel, chronology items
+- `Card.tsx` — card-base class for responsive padding override
+- `PatientSummaryTile.tsx` — KPI value font uses clamp()
+- `ProjectsTile.tsx` — 1 card per view at <480px
+- `useForceSimulation.ts` — 380px constellation height at <480px
+- `tailwind.config.js` — xxs (360px) breakpoint added
+
+Emitting `build.done` to trigger Visual Reviewer for screenshot validation.
+
+## Ralph Coordinator — Iteration 5
+
+### Events handled: build.task.abandoned + build.blocked (stale)
+
+Re-verified all quality gates:
+- `npm run lint` → 0 errors (6 warnings, pre-existing)
+- `npm run typecheck` → clean
+- `npm run build` → succeeds in 4.14s
+
+### Full implementation verification:
+Confirmed all 11 implementation items present and integrated:
+1. DashboardLayout.tsx — MobileBottomNav imported, useIsMobileNav used, responsive padding
+2. Sidebar.tsx — returns null at <600px
+3. MobileBottomNav.tsx — 56px tab bar + Framer Motion drawer
+4. useIsMobileNav.ts — single source of truth (max-width: 599px)
+5. ChatWidget.tsx — bottom offset calc for mobile nav
+6. index.css — all responsive CSS rules present
+7. Card.tsx — card-base class applied
+8. PatientSummaryTile.tsx — clamp(22px, 6vw, 30px) for KPI values
+9. ProjectsTile.tsx — 1 card per view at <480px
+10. useForceSimulation.ts — 380px height at <480px
+11. tailwind.config.js — xxs: 360px breakpoint

+# Mobile Responsiveness Fix Plan (320-430px)
+
+## Overview
+
+At viewport widths 320-430px, the dashboard is broken: sidebar rail steals 64px, padding steals 40px, leaving only 216-326px for content. This plan fixes all issues in priority order, grouped by file.
+
+---
+
+## Phase 1: Sidebar → Bottom Nav Bar (Critical)
+
+### 1A. Add `xxs` breakpoint to Tailwind (`tailwind.config.js`)
+
+**What:** Add a new breakpoint `xxs: '360px'` below the existing `xs: 480px`.
+
+**Why:** Enables Tailwind utility classes for sub-480px styling. Also useful for font/spacing adjustments.
+
+```js
+screens: {
+  'xxs': '360px',  // NEW
+  'xs': '480px',
+  ...
+}
+```
+
+### 1B. Create `MobileBottomNav` component (`src/components/MobileBottomNav.tsx`)
+
+**What:** New component that renders a bottom navigation bar at viewports <600px.
+
+**Collapsed state (default):**
+- Fixed to bottom edge, 56px tall, full width
+- Background: `var(--sidebar-bg)` with top border `var(--border)`
+- Contains: 3 nav icons (Overview, Experience, Skills) + hamburger/menu icon for drawer
+- Icons from existing `navSections` in Sidebar.tsx (reuse `UserRound`, `Workflow`, `Wrench`)
+- Active state: teal accent color, same as sidebar
+- Touch targets: each icon button is 44x44px minimum
+
+**Expanded state (drawer):**
+- Triggered by tapping hamburger icon or swiping up
+- Slides up from bottom using Framer Motion `AnimatePresence` + `motion.div`
+- Max height: 70vh, scrollable
+- Contains: full sidebar content (patient name, details, search, tags, alerts)
+- Extract shared content rendering from `Sidebar.tsx` into reusable pieces
+- Backdrop overlay: same `rgba(26,43,42,0.28)` as current sidebar
+- Close: tap backdrop, tap close button, or swipe down
+
+**Implementation:**
+- Use `window.matchMedia('(max-width: 599px)')` to detect mobile
+- Accept same props as Sidebar: `activeSection`, `onNavigate`, `onSearchClick`
+- Do NOT import from Sidebar — reuse the same data sources (`navSections`, `patient`, `tags`, `alerts`)
+
+### 1C. Modify `Sidebar.tsx`
+
+**What:** Hide the sidebar completely at <600px.
+
+**How:** Add a `useMediaQuery` check or pass an `isMobileNav` prop. When viewport is <600px, return `null` (render nothing). The sidebar rail and overlay are replaced by `MobileBottomNav`.
+
+**Important:** All existing sidebar behavior at >=600px must remain unchanged.
+
+### 1D. Modify `DashboardLayout.tsx`
+
+**What:** Integrate MobileBottomNav and adjust main content area.
+
+**Changes:**
+1. Import and render `<MobileBottomNav>` alongside sidebar
+2. Add CSS class or style for bottom padding on main content when bottom nav is visible: `paddingBottom: 'calc(56px + env(safe-area-inset-bottom))'`
+3. The `dashboard-main` margin-left should be 0 at <600px (since sidebar is hidden)
+
+### 1E. Modify `src/index.css`
+
+**What:** Override `dashboard-main` margin-left at <600px.
+
+```css
+@media (max-width: 599px) {
+  .dashboard-main {
+    margin-left: 0;
+  }
+}
+```
+
+---
+
+## Phase 2: Spacing & Padding Reduction (Critical)
+
+### 2A. Reduce main content padding at small viewports (`DashboardLayout.tsx`)
+
+**What:** Change padding from `p-5` (20px) to a smaller value at <480px.
+
+**How:** Update className: `p-3 xs:p-5 pb-10 md:p-7 md:pb-12 lg:px-8 lg:pt-7 lg:pb-12`
+
+This gives 12px padding at <480px instead of 20px, recovering 16px of usable width.
+
+### 2B. Reduce Card padding at small viewports (`Card.tsx`)
+
+**What:** Reduce `padding: '24px'` to 16px at small viewports.
+
+**How:** Use inline responsive logic or a CSS class. Since Card uses inline styles, detect viewport width or add a CSS class:
+
+Option: Add `className="card-base"` and define:
+```css
+.card-base { padding: 24px; }
+@media (max-width: 479px) {
+  .card-base { padding: 16px !important; }
+}
+```
+
+Or use a custom hook for viewport width and adjust inline.
+
+### 2C. Reduce `chronology-item` padding (`index.css`)
+
+**What:** Reduce `padding: 10px 12px 12px` to tighter values at <480px.
+
+```css
+@media (max-width: 479px) {
+  .chronology-item {
+    padding: 8px 8px 10px;
+  }
+}
+```
+
+---
+
+## Phase 3: KPI Grid Fix (Critical)
+
+### 3A. Make KPI grid responsive (`PatientSummaryTile.tsx`)
+
+**What:** Change KPI grid from hardcoded 2-column to responsive.
+
+**How:** Use a CSS class instead of inline `gridTemplateColumns`:
+
+```css
+/* Default: 2 columns */
+.kpi-grid {
+  display: grid;
+  gap: 10px;
+  grid-template-columns: repeat(2, minmax(0, 1fr));
+}
+
+/* Single column at very narrow viewports */
+@media (max-width: 359px) {
+  .kpi-grid {
+    grid-template-columns: 1fr;
+  }
+}
+```
+
+At 360px+ with 2 columns: each card gets ~160px (after removing sidebar, with 12px padding). That's workable.
+At <360px (iPhone SE): single column, full width.
+
+### 3B. Reduce KPI value font size at narrow viewports (`PatientSummaryTile.tsx`)
+
+**What:** Reduce `fontSize: '30px'` on metric values.
+
+**How:** Use `clamp()` or media query: `fontSize: 'clamp(22px, 6vw, 30px)'` — scales from 22px at 320px to 30px at 500px.
+
+---
+
+## Phase 4: Project Carousel Fix (Critical)
+
+### 4A. Use 1 card per view at <480px (`ProjectsTile.tsx`)
+
+**What:** Change `cardsPerView` logic:
+
+```js
+const cardsPerView = useMemo(() => {
+  if (viewportWidth < 480) return 1    // NEW: 1 card at small mobile
+  if (viewportWidth < 768) return 2
+  return 4
+}, [viewportWidth])
+```
+
+At 320px with no sidebar: usable width ~296px → 1 card at ~296px is great.
+
+### 4B. Reduce card min-height at <480px (`ProjectsTile.tsx`)
+
+**What:** Add a smaller min-height tier:
+
+```js
+if (viewportWidth < 480) return 148
+if (viewportWidth < 640) return 168
+```
+
+---
+
+## Phase 5: Timeline & Text Overflow (Important)
+
+### 5A. Allow timeline badges to wrap (`TimelineInterventionsSubsection.tsx`)
+
+**What:** Change the badge container from `flexShrink: 0` to allow wrapping at narrow widths.
+
+**How:** Add `flexWrap: 'wrap'` to the badge container and remove `flexShrink: 0`.
+
+At very narrow widths, badges will wrap below the title instead of forcing overflow.
+
+### 5B. Ensure ExpandableCardShell doesn't clip text (`ExpandableCardShell.tsx`)
+
+**What:** The inner wrapper has `overflow: 'hidden'` which is needed for animation but could clip header text.
+
+**Status:** Currently OK — the `minWidth: 0` on flex children handles text wrapping. The header has `gap: '8px'` and text naturally wraps. No change needed, but monitor.
+
+---
+
+## Phase 6: Constellation Graph (Important)
+
+### 6A. Reduce constellation height at <480px (`useForceSimulation.ts`)
+
+**What:** Change `getHeight()` to return a smaller height for very narrow viewports:
+
+```js
+function getHeight(width: number, containerHeight?: number | null): number {
+  if (width < 480) return 380    // NEW: shorter for small phones
+  if (width < 768) return 520
+  if (containerHeight && containerHeight > 0) return Math.max(400, containerHeight)
+  return 400
+}
+```
+
+520px is disproportionate at 320px wide. 380px keeps it visible without dominating the view.
+
+---
+
+## Phase 7: Detail Panel Polish (Minor)
+
+### 7A. Reduce detail panel body padding at narrow widths (`DetailPanel.tsx`)
+
+**What:** Change `padding: '24px'` to `padding: '16px'` at <480px.
+
+**How:** Add responsive CSS or inline viewport check:
+
+```css
+@media (max-width: 479px) {
+  .detail-panel .detail-panel-body {
+    padding: 16px;
+  }
+}
+```
+
+Or add a `className` to the body div and use CSS.
+
+### 7B. Reduce detail panel header padding (`DetailPanel.tsx`)
+
+**What:** Change `padding: '20px 24px'` to `padding: '16px'` at <480px.
+
+Same approach as 7A.
+
+---
+
+## Phase 8: Medications/Skills Grid (Minor)
+
+### 8A. Already single-column on mobile (`index.css`)
+
+**Status:** `.medications-grid` is already `grid-template-columns: 1fr` at mobile, going to 3 columns at 768px+. No change needed.
+
+---
+
+## Implementation Order
+
+1. **Phase 1** (Sidebar → Bottom Nav) — Most impactful, recovers 64px
+2. **Phase 2** (Spacing) — Recovers 16-32px more
+3. **Phase 3** (KPI grid) — Fixes cramped cards
+4. **Phase 4** (Carousel) — Fixes tiny project cards
+5. **Phase 5** (Timeline) — Fixes potential text overflow
+6. **Phase 6** (Constellation) — Better proportions
+7. **Phase 7** (Detail panel) — Polish
+8. **Phase 8** (Skills grid) — No change needed
+
+## Width Budget After Fixes
+
+| Viewport | Sidebar | Padding | Usable Width | Before |
+|----------|---------|---------|--------------|--------|
+| 320px    | 0px     | 24px    | **296px**    | 216px  |
+| 360px    | 0px     | 24px    | **336px**    | 256px  |
+| 375px    | 0px     | 24px    | **351px**    | 271px  |
+| 400px    | 0px     | 24px    | **376px**    | 296px  |
+| 430px    | 0px     | 24px    | **406px**    | 326px  |
+
+*At <480px: 12px padding each side = 24px total. Card padding: 16px each side = 32px total. Content area inside card: 232-374px.*

-# Task: Constellation Hover Focus Mode With Global Dimming
+# Task: Fix Mobile Responsiveness for Small Viewport Widths (≤430px)
 
-Implement a focused hover mode so that when a user hovers a skill or node in the constellation area, non-related UI darkens and only the relevant relationship remains emphasized.
+The portfolio website is broken on phones with viewport widths around 400px. Text overflows off-screen, elements are hidden behind `overflow: hidden`, and layout components are sized inappropriately for small screens.
+
+## Context
+
+- **Tech stack:** React + TypeScript + Tailwind CSS + Framer Motion + D3
+- **Dev server:** `npm run dev` (localhost:5173)
+- **Quality gates:** `npm run lint && npm run typecheck && npm run build`
+- **Smallest configured breakpoint:** `xs: 480px` in tailwind.config.js — there is no sub-480px handling
+- **Key layout file:** `src/components/DashboardLayout.tsx` orchestrates all dashboard tiles
+- **CSS media queries:** `src/index.css` contains most custom responsive rules
+- **Tailwind config:** `tailwind.config.js` defines breakpoints and theme
+
+## Target Viewports
+
+Test and fix at these widths (all portrait orientation, 812px height):
+- **320px** — iPhone SE / smallest realistic phone
+- **360px** — Common Android (Samsung Galaxy S series)
+- **375px** — iPhone 12 mini / iPhone SE 3rd gen
+- **390px** — iPhone 14
+- **400px** — User's specific device (primary target)
+- **414px** — iPhone 8 Plus / larger phones
+- **430px** — iPhone 14 Pro Max
+
+## Known Issues (from codebase analysis)
+
+### Critical
+1. **Sidebar must become a bottom nav bar at <600px** — The current sidebar is a 304px-wide overlay on mobile, leaving only 96px for content at 400px. At viewport widths below 600px, replace the sidebar with a **bottom navigation bar** that:
+   - **Collapsed state (default):** A slim fixed bar along the bottom edge of the screen with icon-based navigation items (like a mobile tab bar / iOS-style bottom nav). Should not obscure content — main content area accounts for its height.
+   - **Expanded state (on tap/click):** Slides up as a drawer/sheet showing the full sidebar content (patient name, navigation links, etc.). Tapping the bar or a close affordance collapses it back down.
+   - The existing sidebar behavior for viewports ≥600px should remain completely unchanged.
+   - Use Framer Motion for the drawer slide animation, consistent with existing animation patterns.
+2. **KPI grid forces 2 columns** — `repeat(2, minmax(0, 1fr))` creates cramped cards at small widths. Values use `30px` font.
+3. **Timeline text silently clipped** — `overflow: hidden` on Card.tsx hides content with no visual indication (no ellipsis, no wrapping).
+4. **Project carousel cards too small** — At 400px with 2 cards per view, each card is only ~194px wide.
+
+### Important
+5. **Constellation graph** — 520px height at <768px may be disproportionate; needs better sizing.
+6. **No sub-480px breakpoint** — The smallest Tailwind breakpoint is `xs: 480px`, leaving 320-479px unhandled.
+
+### Minor
+8. **Padding/spacing** — `p-5` (20px) main content + `24px` card padding eats significant space at 400px.
+9. **Detail panel header** — Close button (44px) + title cramped at narrow widths.
+10. **Skills/medications grid** — May need column count reduction at small widths.
 
 ## Requirements
 
-- Support hover-triggered focus mode from:
+- **All text must be visible** — no text clipped by `overflow: hidden` without ellipsis or wrapping. Truncated text needs `text-overflow: ellipsis` with title attribute for accessibility.
-  - constellation node hover
+- **All interactive elements must be reachable** — nothing hidden off-screen or behind other elements.
-  - skill pill hover
+- **Touch targets** — minimum 44x44px for interactive elements.
-- In focus mode, darken non-related UI across the page, including:
+- **Readable font sizes** — minimum 12px body text, 14px primary content.
-  - graph axis/background
+- **No horizontal scroll** — page must never scroll horizontally at any target viewport.
-  - unrelated graph nodes/labels/links
+- **Maintain visual identity** — keep PMR aesthetic, teal/coral palette, existing design language. Adapt proportionally, don't radically redesign.
-  - unrelated timeline and dashboard elements
+- **Respect existing patterns** — use Tailwind classes where possible, use existing CSS custom properties, follow project conventions.
-- Keep the following elements visually emphasized (not darkened):
-  - hovered skill pill
-  - hovered/active constellation node
-  - connection lines between related node/skill items
-  - timeline series item related to that skill/node
-- On hover exit, restore default appearance cleanly with no stuck state.
-- Preserve existing click behavior, keyboard behavior, and detail panel opening logic.
-- Respect reduced-motion preferences and existing accessibility patterns.
-
-## Likely Files To Update

-- `src/components/DashboardLayout.tsx`
-- `src/hooks/useConstellationInteraction.ts`
-- `src/hooks/useConstellationHighlight.ts`
-- `src/components/TimelineInterventionsSubsection.tsx`
-- `src/components/RepeatMedicationsSubsection.tsx`
-- `src/components/ExpandableCardShell.tsx`
-- `src/index.css`
-
-Update additional files only if necessary.
 
 ## Success Criteria
 
 All of the following must be true:
 
-- [ ] Hovering a constellation node enters focus mode with global dimming.
+- [ ] `npm run lint` passes with zero errors
-- [ ] Hovering a skill pill enters focus mode with global dimming.
+- [ ] `npm run typecheck` passes with zero errors
-- [ ] In focus mode, only the relevant node + relationship links + related timeline series item + active skill pill remain visually highlighted.
+- [ ] `npm run build` succeeds
-- [ ] Graph axis/background visibly darken during focus mode.
+- [ ] At 320px viewport: no horizontal scrollbar, all text readable, no content clipped without indication
-- [ ] Focus mode exits correctly on mouse leave with no lingering darkened state.
+- [ ] At 360px viewport: same as above
-- [ ] Existing interactions (role click, skill click, panel open, timeline expand/collapse) still work.
+- [ ] At 375px viewport: same as above
-- [ ] `npm run lint` passes.

+- [ ] At 414px viewport: same as above
-- [ ] Playwright MCP evidence confirms behavior for both node-hover and skill-pill-hover scenarios.
+- [ ] At 430px viewport: same as above
-
+- [ ] At <600px: sidebar is replaced by a bottom nav bar with collapsed (tab bar) and expanded (drawer) states
-## Playwright MCP Verification
+- [ ] Bottom nav bar does not obscure page content in collapsed state (content has bottom padding/margin to account for it)
-
+- [ ] Bottom nav drawer expands on tap and shows full navigation content
-Reviewer must validate with Playwright MCP and record evidence in `.ralph/review.md`:
+- [ ] Bottom nav drawer can be collapsed back down
-
+- [ ] At ≥600px: existing sidebar behavior is completely unchanged
-- Run or confirm dev server at `http://localhost:5173`
+- [ ] KPI cards are readable with appropriate font sizing
-- Capture baseline screenshot before hover
+- [ ] Timeline entries show full text or have proper ellipsis truncation
-- Hover a constellation node and capture screenshot
+- [ ] Project carousel cards are adequately sized (consider 1 card per view if needed)
-- Hover a skill pill and capture screenshot
+- [ ] Constellation graph fits within viewport without excessive scrolling
-- In both hover screenshots, verify:
+- [ ] Desktop/tablet layouts (768px+) remain unchanged and unbroken
-  - unrelated areas are darkened
-  - related graph + timeline + skill elements remain emphasized
 
 ## Constraints
 
-- Do not add new dependencies.
+- Do NOT change boot sequence, ECG animation, or login screen (already handle small screens)
-- Follow existing TypeScript/React conventions and current styling system.
+- Do NOT change D3 force simulation logic — only container sizing
-- Keep changes focused to this feature only.
+- Do NOT add new npm dependencies
-- If a blocker repeats with identical evidence across 3 cycles, escalate in `.ralph/review.md` instead of forcing completion.
+- Do NOT remove existing features or functionality
+- Keep changes minimal and focused — fix responsiveness, don't redesign
+- Preserve all existing breakpoint behavior for md (768px) and above
+
+## Visual Validation Method
+
+Use Playwright MCP to:
+1. Navigate to `http://localhost:5173` (dev server must be running)
+2. Get past boot sequence + ECG + login to reach dashboard
+3. Set viewport to each target width × 812px height
+4. Take screenshots of dashboard at each viewport
+5. Visually inspect for: overflow, clipping, cramped text, unreachable elements
+6. Scroll through full page and verify no content is hidden
 
 ## Status
 
-Track progress in `.ralph/plan.md`, `.ralph/build.md`, and `.ralph/review.md`.
+Track progress here. When all success criteria are met, print LOOP_COMPLETE.
-When all success criteria are met, print `LOOP_COMPLETE`.

+      2. Use Playwright MCP to launch a browser and navigate to http://localhost:5173
+
+      3. Get past the boot sequence to reach the dashboard:
+         - Wait for boot sequence to complete
+         - Click through login screen if present
+         - Wait until dashboard is fully rendered
+
+      4. For each target viewport width (320, 360, 375, 390, 400, 414, 430px):
+         a. Set viewport to {width}x812px
+         b. Take a screenshot
+         c. Visually inspect for:
+            - Horizontal scrollbar (body must not scroll horizontally)
+            - Text clipped/hidden without ellipsis
+            - Elements overlapping or pushed off-screen
+            - Text too small to read (< 12px)
+            - Interactive elements too small to tap (< 44px)
+            - Excessive empty space or cramped layouts
+            - Bottom nav bar should be visible at bottom of screen (not a sidebar)
+         d. Scroll through the full page and check each section
+         e. Test the bottom nav bar:
+            - Verify collapsed state shows icon-based navigation at bottom edge
+            - Tap/click to expand the drawer and verify full nav content appears
+            - Verify drawer can be collapsed back
+            - Verify collapsed bar does not obscure page content
+         f. Record findings
+
+      5. Verify desktop is not broken:
+         - Set viewport to 1280x800
+         - Take screenshot
+         - Verify dashboard layout is unchanged
+
+      ## Writing Your Review
+
+      Write findings to .ralph/review.md:
+
+      ```
+      # Visual Review
+
+      ## Viewport Results
+
+      ### 320px
+      - [PASS/FAIL] [description]
+
+      ### 360px
+      - [PASS/FAIL] [description]
+
+      (... each viewport ...)
+
+      ### Desktop (1280px)
+      - [PASS/FAIL] Must be unchanged
+
+      ## Issues Found
+      - [ ] [Specific issue with component name and description]
+
+      ## Verdict
+      [APPROVED / CHANGES_REQUESTED]
+      ```
+
+      If ALL viewports pass and desktop is unchanged, print LOOP_COMPLETE.
+
+      If issues remain, write specific actionable feedback and emit review.changes_requested.
+
+      CIRCUIT BREAKER: If materially identical issues persist across 3 consecutive
+      reviews, write to .ralph/review.md with status "NEEDS_HUMAN", note recurring
+      issues and what was attempted, then print LOOP_COMPLETE.
