 ## Project Overview
-Interactive CV/portfolio website for Andy Charlwood with a distinctive three-phase loading experience: terminal boot sequence → ECG canvas animation → main content. Built as a React SPA with TypeScript and Vite.
+Interactive CV/portfolio for Andy Charlwood, presented as a premium clinical information system. The concept: *what if a GP surgery's patient record system were redesigned by a luxury product studio?* The structure and metaphor of a real clinical system (patient banner, sidebar navigation, record sections) — but elevated with refined typography, considered motion, and atmospheric depth.
 **This is NOT a faithful NHS system clone.** It's a showcase portfolio that *evokes* the feel of clinical software while being distinctly beautiful. The clinical metaphor is the creative conceit; the execution should feel premium and elegant.

-
+4. **PMRInterface** — The main portfolio experience: patient banner + clinical sidebar + scrollable content views.
 Total boot-to-content time must be ≤10 seconds.
 ### Key Patterns
- **Scroll reveals**: `useScrollReveal` hook wraps IntersectionObserver with trigger-once semantics. Used by every content section. Never use scroll event listeners.
+- **Canvas ECG**: `ECGAnimation.tsx` does imperative canvas drawing with requestAnimationFrame — flatline → 3 heartbeats (40px→60px→100px) → mask-based letter tracing → exit.
- **Active nav tracking**: `useActiveSection` hook tracks which section is in viewport for FloatingNav highlighting.
+- **Clinical sidebar navigation**: `ClinicalSidebar.tsx` provides hash-routed view switching with keyboard shortcuts (Alt+1-7, arrow keys, "/" for search).
- **Staggered animations**: Components use index-based delays (`baseDelay + index * 100`) with Framer Motion.
+- **Patient banner condensation**: `PatientBanner.tsx` uses IntersectionObserver via `useScrollCondensation` hook — full banner (80px) condenses to 48px on scroll.
- **SVG skill circles**: `Skills.tsx` uses `strokeDashoffset = circumference * (1 - level / 100)` with `-90deg` rotation to start from 12 o'clock.
+- **Staggered entrance animations**: Framer Motion variants with sequenced delays (banner → sidebar → content).
- **Canvas ECG**: `ECGAnimation.tsx` does imperative canvas drawing with requestAnimationFrame — flatline → 3 heartbeats (40px→60px→100px) → letter tracing → exit.
+- **View switching**: Instant — no crossfade or slide between views. Content fades in once on initial load only.
 - **Expandable rows**: Consultation entries, medication rows, and problem entries expand in-place with height animation.
 - **Responsive breakpoints**: Desktop (full sidebar + banner), Tablet (icon-only sidebar), Mobile (bottom nav bar).
 ### Path Aliases
 `@/` maps to `./src/` (configured in both `vite.config.ts` and `tsconfig.json`).
 ### Styling
 Tailwind CSS with custom design tokens in `tailwind.config.js`:
 - **Colors**: teal `#00897B` (primary), coral `#FF6B6B` (accent), ECG palette (green/cyan/dim)
 - **Fonts**: Plus Jakarta Sans (primary), Inter Tight (secondary), Fira Code (mono/terminal)
 - **Breakpoints**: xs 480px, sm 640px, md 768px, lg 1024px, xl 1280px
 - Inline styles only for dynamic values that Tailwind can't express (e.g., computed `strokeDashoffset`).
 ### Type System
-All data types live in `src/types/index.ts`. Strict TypeScript — no `any` types. One component per file with typed props interfaces.

 ## Design Direction: Clinical Luxury
 The aesthetic direction is **"Clinical Luxury"** — the precision and information density of a medical records system, married to the refinement of high-end product design. Think Bloomberg Terminal redesigned by a Swiss design house.
 ### Tone
 - **Precise, not cold.** Every element has a reason. Spacing is generous but intentional.
 - **Structured, not rigid.** The grid and hierarchy of clinical software, but with room to breathe.
 - **Technical, not sterile.** Monospace data, status indicators, and coded entries create authentic texture.
 - **Elegant, not decorative.** No gratuitous ornament. Beauty comes from proportion, contrast, and type.
 ### Typography
 Typography is the primary vehicle for premium feel. Avoid generic system fonts.
 - **UI / Body**: Use a distinctive geometric or humanist sans-serif with character — **not** Inter, Roboto, or system defaults. Choose something with personality that still reads cleanly at small sizes (11-14px range). Candidates: Satoshi, General Sans, Outfit, DM Sans, or similar. The chosen font should feel "designed" rather than "default."
 - **Monospace / Data**: Geist Mono for timestamps, coded entries, registration numbers, and tabular data. This creates the "technical texture" that sells the clinical metaphor.
 - **Terminal phase**: Fira Code — locked, do not change.
 - **Type scale**: Keep it tight. Clinical systems use small text. Headings 15-18px, body 13-14px, labels 11-12px. Precision over drama.
 - **Weight hierarchy**: Use weight (400/500/600/700) rather than size to establish hierarchy. Bold section headers, medium labels, regular body.
 ### Color Palette
 The palette anchors on NHS Blue as the institutional accent, with a predominantly dark sidebar + light content split that creates natural drama.
 - **NHS Blue `#005EB8`** — The single strong accent color. Used for active states, links, buttons, interactive elements. This IS the brand color of the clinical metaphor.
 - **Dark sidebar `#1E293B`** — Creates gravitas. The "serious software" feel comes from this dark chrome.
 - **Patient banner `#334155`** — Slightly lighter than sidebar. The information-dense header bar.
 - **Content background** — Not flat gray. Consider a very subtle warm tint, or a faint noise/grain texture overlay on `#F5F7FA` to add depth. The content area should feel like paper, not a spreadsheet.
 - **Cards `#FFFFFF`** — Clean white with refined shadows (layered, not single-value). Cards should feel like they float slightly above the content surface.
 - **Status colors**: Green `#22C55E`, Amber `#F59E0B`, Red `#EF4444` — used sparingly for traffic-light indicators. Always paired with text labels, never as sole signifier.
 - **Text**: Primary `#111827`, Secondary `#6B7280`, Muted `#94A3B8`. Use the full range for hierarchy.
 ### Shadows & Depth
 Real clinical software is flat and border-heavy. This project should use shadows to create subtle layered depth:
 - **Cards**: Multi-layered shadow — e.g., `0 1px 2px rgba(0,0,0,0.04), 0 4px 12px rgba(0,0,0,0.03)`. Gentle, not Material Design dramatic.
 - **Sidebar**: Optional very subtle inner shadow or glow at the right edge where it meets content.
 - **Patient banner**: Subtle drop shadow below to separate from content.
 - **Hover states**: Cards may lift very slightly on hover (1-2px translate + shadow deepen). Keep it restrained.
 ### Motion
 Motion should feel considered and premium, never flashy:
 - **Entrance animations**: The PMR interface materializes in sequence — banner slides down → sidebar slides from left → content fades in. Quick (200-300ms) with easing.
 - **Login transition**: Card scales slightly and fades. Background carries over to PMR (both are `#1E293B`-derived).
 - **View switching**: Instant, no transition between views. This preserves the "software application" feel.
 - **Expandable content**: Height-only animation, 200ms ease-out. Content grows/shrinks — no opacity fade.
 - **Hover states**: Subtle, immediate. Background color shifts, not transforms. Think: OS-level responsiveness.
 - **Clinical alert**: Spring animation for entrance (Framer Motion `type: "spring"`). Dismiss: icon crossfade → height collapse.
 - **`prefers-reduced-motion`**: All animations skip to final state. No exceptions.
 ### Spatial Composition
 - **Generous but structured.** More whitespace than a real clinical system. Cards have 16-24px padding. Sections breathe.
 - **Clear visual hierarchy.** Section headers (uppercase, small, tracked-out) → content. No ambiguity about what's a label vs. data.
 - **Two-column summary grid** on desktop, single column on mobile. Cards span full width or half width — no orphan columns.
 - **Tables** use proper `<table>` markup with styled headers on a light gray background. Alternating row colors. This is where the clinical authenticity lives.
 ### What Makes It Memorable
 The distinctiveness comes from the *contrast between structure and polish*:
 - A dark, serious sidebar next to warm, airy content
 - Small, precise monospace data in a field of generous whitespace
 - NHS blue punching through an otherwise muted palette
 - The clinical metaphor itself — "Patient Record" for a CV is unexpected and charming
 - The boot sequence → ECG → login flow is theatrical in a way that real clinical software never is
 ## Styling
 Tailwind CSS with custom design tokens in `tailwind.config.js`:
 - **Color tokens**: All PMR-prefixed tokens in Tailwind config (`pmr-sidebar`, `pmr-banner`, `pmr-nhsblue`, etc.)
 - **Fonts**: Configured as `font-inter`, `font-geist` (monospace) in Tailwind — these need updating when the primary UI font changes.
 - **Breakpoints**: xs 480px, sm 640px, md 768px, lg 1024px, xl 1280px
 - **Border radius**: 4px default for cards/inputs (clinical precision). 12px exception for login card only.
 - Inline styles only for dynamic values that Tailwind can't express.
 - CSS custom properties in `index.css` for both boot/ECG phase tokens and PMR phase tokens.
 ## Guardrails
- Boot sequence text and colors must match `References/concept.html` exactly (CLINICAL TERMINAL v3.2.1 format).
+- **Boot sequence**: Text, colors, and timing must match `References/concept.html` exactly. **Do not modify.**
- ECG animation timing/amplitudes/color transitions must match the concept reference.
+- **ECG animation**: Timing, amplitudes, color transitions, and mask-based text reveal must match the concept reference. **Do not modify.**
- CV content sourced from `References/CV_v4.md` — roles, dates, and achievement numbers must be accurate.
+- **CV content**: Sourced from `References/CV_v4.md` — roles, dates, and achievement numbers must be accurate.
- Icons via `lucide-react`, not unicode symbols.
+- **Icons**: Via `lucide-react`, not unicode symbols.
 - **Accessibility**: WCAG 2.1 AA compliance. Semantic HTML, ARIA attributes, keyboard navigation, `prefers-reduced-motion` support throughout.
 - **No generic aesthetics**: Every design decision should feel intentional. If a component could appear in any random SaaS template, it needs more character.

Also read `ECGCombined.tsx` in the project root for the Remotion reference implementation of the mask-based text reveal. This task covers the full pre-login animation flow: (a) **Refactor BootSequence.tsx** — replace hardcoded HTML strings with a clean config-driven structure. Each line type (header, field, separator, module, ready) maps to a React component. Keep the same visual output: green-on-black terminal, Fira Code font, 220ms staggered line reveals, `#00ff41` bright green / `#3a6b45` dim green / `#00e5ff` cyan labels. (b) **Cursor → dot transition** — the blinking green cursor at the end of boot must smoothly morph into the ECG's glowing trace dot. Capture the cursor's screen position and pass it to ECGAnimation as a `startPosition` prop. The cursor stops blinking, transitions from block to circular glow (~300ms), then begins moving rightward as the ECG trace dot. (c) **ECG start sync** — ECGAnimation must start its trace from the cursor position (not the far left edge). The first beat begins after a flat gap from the cursor position. Shift the world-space origin so the trace starts where the cursor was. (d) **Mask-based text reveal** — adopt ECGCombined.tsx's technique where pre-rendered stroke-only text is revealed by a wipe mask following the trace head (instead of the current alpha fade approach). Keep the current character spacing (`LETTER_W`, `LETTER_G`, `SPACE_W`) and heartbeat waveform. Add connector lines between letters at baseline. (e) **Keep**: heartbeat shape, beat timing (0.3→0.55→0.85→1.0 amplitude), canvas rendering, viewport scrolling, flatline draw, scanlines, vignette, background transition to `#1E293B`. (f) Respect `prefers-reduced-motion` — with reduced motion, skip animation and show static final frame or jump to login.

(d) Username field types `A.CHARLWOOD` at 30ms/char in **Geist Mono** font. (e) Password field fills 8 dots at 20ms/dot. (f) Blinking cursor (530ms interval) in active field. (g) "Log In" button: NHS blue `#005EB8`, full width, pressed state darkens to `#004494`. (h) After submit: card scales to 103% and fades out over 200ms. (i) Respect `prefers-reduced-motion`.

Hover fills with NHS blue bg + white text. (d) Condensed banner 48px: single line with name, NHS number, status, action buttons only. Triggers at 100px scroll via IntersectionObserver.

 ## Design Philosophy
 This is a **premium portfolio** that uses the structure and metaphor of a GP clinical system — not a faithful NHS software clone. Real clinical systems (EMIS Web, SystmOne) are dense, border-heavy, and purely functional. We keep their *structure* (patient banner, sidebar navigation, record sections, tables, status indicators) but elevate the *execution* with refined typography, atmospheric depth, and considered whitespace.
 The goal is contrast: clinical precision married to luxury refinement. The "wow" comes from recognizing the clinical metaphor while being surprised by how good it looks.
 ---
 ## Color Palette
-This design is **light-mode only**. Clinical record systems operate in light mode — high ambient lighting in consulting rooms demands white backgrounds and dark text. A dark mode would break the metaphor.
+**Light-mode only.** The metaphor demands it — clinical systems operate under bright consulting room lights. No dark mode.
 **Backgrounds:**
- Main content area: `#F5F7FA` (cool light gray — the content background of EMIS/SystmOne)
+- Main content area: `#F5F7FA` — cool light gray base. Add atmospheric depth: a very faint noise/grain texture overlay, or a subtle warm tint, so it feels like quality paper rather than a flat spreadsheet. The content surface should have *presence*.
- Card/panel surfaces: `#FFFFFF` (white)
+- Card/panel surfaces: `#FFFFFF` — clean white. Cards float above the content surface via layered shadows (see Surfaces section).
- Sidebar: `#1E293B` (dark blue-gray — EMIS-style dark navigation panel)
+- Sidebar: `#1E293B` — dark blue-gray. The gravitas anchor. This dark chrome is what makes it feel like "serious software."
- Patient banner: `#334155` (lighter blue-gray with white text)

- Primary text: `#111827` (gray-900 — near-black for maximum readability)
+- Primary: `#111827` (gray-900) — near-black for maximum readability
- Secondary text: `#6B7280` (gray-500)

+- Muted: `#94A3B8` (slate-400) — timestamps, tertiary info
 - On dark surfaces: `#FFFFFF` (white primary), `#94A3B8` (slate-400 secondary)

 ## Typography
-Clinical systems use system fonts — Inter or Segoe UI for general text, monospace for coded entries and data values. No decorative fonts, no variable tracking. Functional typography optimized for scanning dense tables.
+Typography is the primary vehicle for the premium feel. The font choice must feel *designed* — intentional and distinctive — while still reading cleanly at small clinical-system sizes (11-14px).
- **Patient banner name:** Inter 600, 20px (not huge — clinical systems don't emphasize the patient name with large type)
+**Font selection:**
- **Patient banner details:** Inter 400, 14px
+- **UI / Body font**: Choose a distinctive geometric or humanist sans-serif with character. **Do not use** Inter, Roboto, Arial, or system-ui defaults — these read as generic/AI-generated. Candidates: **Satoshi**, **General Sans**, **Outfit**, **DM Sans**, or similar. The chosen font should have personality at 13px. Whichever is selected, configure it as the primary `font-family` across all UI elements.
- **Sidebar navigation labels:** Inter 500, 14px, white
+- **Monospace / Data font**: **Geist Mono** — for timestamps, coded entries, registration numbers, NHS numbers, tabular data values. This monospace texture is what sells the "clinical software" feel. Falls back to Fira Code.
- **Section headings (within main area):** Inter 600, 18px
+- **Terminal phase**: **Fira Code** — locked, do not change.
- **Consultation entry titles:** Inter 600, 16px
+
- **Body text / descriptions:** Inter 400, 14px, line-height 1.6
+**Type scale (tight, clinical):**
- **Table headers:** Inter 600, 13px, uppercase, letter-spacing 0.03em, gray-500
+- Patient banner name: [UI font] 600, 20px
- **Table data cells:** Inter 400, 14px
+- Patient banner details: [UI font] 400, 14px
- **Coded entries / data values:** Geist Mono 400, 13px
+- Sidebar navigation labels: [UI font] 500, 14px, white
- **Clinical codes (SNOMED-style):** Geist Mono 400, 12px, gray-400
+- Section headings (main area): [UI font] 600, 15-18px
- **Timestamps:** Geist Mono 400, 12px
+- Consultation entry titles: [UI font] 600, 15-16px
- **Alert banner text:** Inter 500, 14px
+- Body text / descriptions: [UI font] 400, 13-14px, line-height 1.6
 - Table headers: [UI font] 600, 12-13px, uppercase, letter-spacing 0.03-0.05em
 - Table data cells: [UI font] 400, 13-14px
 - Labels / metadata: [UI font] 500, 11-12px
 - Coded entries / data values: Geist Mono 400, 12-13px
 - Clinical codes (SNOMED-style): Geist Mono 400, 11-12px, gray-400
 - Timestamps: Geist Mono 400, 11-12px
 - Alert banner text: [UI font] 500, 14px
 **Hierarchy through weight, not size.** Use 400/500/600/700 weight variations within a narrow size range. Bold section headers, medium labels, regular body. This keeps the clinical density while creating clear scannable hierarchy.

 ## Spacing and Layout
 More generous than real clinical software. The clinical metaphor provides structure; the extra breathing room provides luxury.
 - **Sidebar width:** 220px (fixed, desktop). Collapses to 56px (icon-only) on tablet.
 - **Patient banner height:** 80px (full), 48px (condensed/sticky)
- **Main content max-width:** No max-width — clinical systems fill available space. Content flows within the area between sidebar and viewport edge.
+- **Main content max-width:** None — fills available space between sidebar and viewport edge.
- **Main content padding:** 24px
+- **Main content padding:** 24px (desktop), 16px (mobile)
- **Card padding:** 16px (clinical systems are more compact than marketing sites)
+- **Card padding:** 16-24px — more generous than real clinical systems. Content should breathe inside cards.
- **Border radius:** 4px for cards and inputs (clinical systems use minimal rounding — 4px, not 12px or 16px)
+- **Border radius:** 4px default for cards, inputs, buttons (clinical precision). 12px exception for the login card only.
 - **Table row height:** 40px
 - **Section spacing:** 24px between content blocks
- **Base unit:** 4px — tighter spacing than typical, reflecting clinical system density
+- **Base unit:** 4px grid — but use it with more generosity than a real clinical system would

- **All cards:** `1px solid #E5E7EB` (gray-200) border, `4px` border-radius, no shadow (or at most `0 1px 2px rgba(0,0,0,0.03)`)
+This is where we diverge most from real clinical software. Real systems are flat and border-heavy. This project uses **shadows and layering** to create premium depth — while keeping borders where they're authentically clinical (tables, input fields).
- **Table cells:** `1px solid #E5E7EB` borders (all sides)
+
- **Sidebar border:** `1px solid #334155` (subtle right border in a slightly lighter shade)
+**Cards:**
- **Patient banner border:** `1px solid #475569` bottom border
+- Border: `1px solid #E5E7EB` (keep the clinical border — it's authentic)
- **Input fields:** `1px solid #D1D5DB` border, `4px` radius, `#FFFFFF` background, `8px 12px` padding
+- Shadow: Multi-layered — `0 1px 2px rgba(0,0,0,0.04), 0 4px 12px rgba(0,0,0,0.03)`. Gentle float, not Material Design dramatic.
- **Active/selected rows:** `#EFF6FF` background (very subtle blue tint) — this is how EMIS highlights the selected row
+- Border-radius: `4px`
 - Hover: Cards may lift very slightly — 1-2px translateY + shadow deepens to `0 2px 4px rgba(0,0,0,0.06), 0 8px 16px rgba(0,0,0,0.04)`. Restrained, not bouncy.
 - Card headers: Light gray `#F9FAFB` background with `1px solid #E5E7EB` bottom border. Uppercase title in [UI font] 600, 12-13px. This is the most "clinical" element — keep it precise.
 **Tables:**
 - Full `<table>` markup with styled headers — this is where clinical authenticity lives.
 - Table headers: `#F9FAFB` background, `1px solid #E5E7EB` borders.
 - Alternating rows: `#FFFFFF` / `#F9FAFB` — subtle but scannable.
 - Row hover: `#EFF6FF` background (blue tint).
 - Cell borders: `1px solid #E5E7EB` — keep full borders on tables. This is authentic.
 **Sidebar:**
 - Background: `#1E293B`
 - Right edge: `1px solid #334155` + optional very subtle glow/shadow where it meets the content area.
 - The sidebar should feel solid and authoritative against the lighter content.
 **Patient banner:**
 - Background: `#334155`
 - Bottom: Subtle drop shadow `0 2px 8px rgba(0,0,0,0.12)` to separate from content below.
 - Bottom border: `1px solid #475569`
 **Input fields:**
 - Border: `1px solid #D1D5DB`, `4px` radius, `#FFFFFF` background, `8px 12px` padding
 - Focus: NHS blue border + `box-shadow: 0 0 0 3px rgba(0,94,184,0.15)` — refined focus ring.

 ## Motion
-Clinical systems are fast and functional. Animations are minimal and purposeful — no spring physics, no bouncy transitions. Everything is immediate or uses simple ease-out.
+Motion should feel **considered and premium** — never flashy, never gratuitous. Every animation has a purpose: to orient the user, to reward interaction, or to create a moment of polish.
- **Navigation switches:** Instant content swap. No crossfade, no slide. When you click a sidebar item, the main content area replaces immediately — just like clicking a tab in EMIS.
+**PMR entrance sequence (login → PMR transition):**
- **Consultation expand/collapse:** Height animation, 200ms, `ease-out`. No opacity fade — the content simply grows/shrinks.
+- Patient banner slides down: 200ms, ease-out
- **Alert banner entrance:** Slide down from top, 250ms, with a subtle spring overshoot (this is the one exception — alerts are meant to demand attention).
+- Sidebar slides from left: 250ms, ease-out, 50ms delay
- **Alert acknowledge:** The alert shrinks in height to zero (200ms) with a small green checkmark that flashes briefly.
+- Content fades in: 300ms, 100ms delay after sidebar
- **Hover states:** Background-color transitions, 100ms. No transforms, no lifts. Just color.
+- This staggered materialization is the single most impactful animation moment.
- **Login typing:** Character-by-character reveal using `setInterval` (30ms per character for username, 20ms per dot for password).
+
- **Patient banner scroll condensation:** Smooth height transition (200ms) from full (80px) to condensed (48px) as user scrolls past the first 100px of content.
+**Navigation switches:** Instant content swap. No crossfade, no slide. This preserves the "software application" feel — clinical systems switch tabs instantly.
- **`prefers-reduced-motion`:** Typing animation completes instantly (full text appears), alert slides are replaced with fade-in, expand/collapse is instant.
+
 **Expandable content:** Height-only animation, 200ms, `ease-out`. Content grows/shrinks — no opacity fade.
 **Clinical alert entrance:** Spring animation (Framer Motion `type: "spring"`, moderate damping). This is the one element that *demands attention* — the spring overshoot is earned here.
 **Alert acknowledge:** Warning icon cross-fades to green checkmark (200ms) → hold 200ms → alert height collapses (200ms ease-out).
 **Hover states:** Subtle and immediate. Background-color transitions at 100ms. Card lifts are 1-2px max with shadow deepening. Think: OS-level responsiveness, not playful bouncing.
 **Login typing:** Character-by-character reveal: 30ms/char for username, 20ms/dot for password. Cursor blink at 530ms.
 **Patient banner condensation:** Smooth height transition (200ms) from 80px → 48px as user scrolls past 100px. Buttery smooth, no jank.
 **`prefers-reduced-motion`:** All animations skip to final state instantly. Typing completes immediately. Alert appears without slide. Expand/collapse is instant. No exceptions.

 ## What Makes This Design Distinctive
 The memorability comes from **contrasts**:
 - Dark, serious sidebar next to warm, airy content
 - Small, precise monospace data in generous whitespace fields
 - NHS blue punching through an otherwise muted, restrained palette
 - Clinical structure (tables, status dots, coded entries) executed with luxury refinement (shadows, spacing, typography)
 - The boot → ECG → login theatrical sequence, then suddenly: a premium application
 If any component could be dropped into a generic SaaS dashboard without looking out of place, it needs more character.
