+# Progress Log — Login Screen Rework
+# Branch: ralph/login-screen-rework
+# Started: 2026-02-15
+
+## Codebase Patterns
+
+### Project Structure
+- Components in `src/components/`, tiles in `src/components/tiles/`
+- Data files in `src/data/`
+- Types in `src/types/pmr.ts` and `src/types/index.ts`
+- Hooks in `src/hooks/`, Contexts in `src/contexts/`, Lib in `src/lib/`
+- Path alias: `@/` maps to `./src/`
+
+### Phase Management
+- App.tsx controls phase: 'boot' -> 'ecg' -> 'login' -> 'pmr'
+- BootSequence.tsx, ECGAnimation.tsx — LOCKED, do not modify
+- LoginScreen.tsx bridges to dashboard
+
+### Typography
+- Elvaro Grotesque (`font-ui`, `var(--font-ui)`) — primary UI font
+- Blumir (`font-ui-alt`) — alternative variable font
+- Geist Mono (`font-geist`, `var(--font-geist-mono)`) — timestamps, data values
+- Fira Code (`font-mono`) — boot/ECG terminal only
+- Do NOT use Inter, Roboto, DM Sans, or system defaults
+
+### Design Tokens (index.css CSS variables)
+- --surface: #FFFFFF (card/topbar background)
+- --bg-dashboard: #F0F5F4 (warm sage content background)
+- --accent: #0D6E6E (teal primary)
+- --accent-hover: #0A8080
+- --accent-light: rgba(10,128,128,0.08)
+- --border: #D4E0DE (structural borders)
+- --border-card: #E4EDEB (card/inner borders)
+- --text-primary: #1A2B2A
+- --text-secondary: #5B7A78
+- --text-tertiary: #8DA8A5
+- --sidebar-width: 304px
+- --topbar-height: 56px
+
+### Known Dependencies
+- React 18.3.1, TypeScript, Vite, Tailwind CSS
+- Framer Motion 11.15.0, Lucide React 0.468.0, fuse.js 7.0.0
+
+### Phase Rendering (post US-006)
+- Login phase now renders BOTH DashboardLayout and LoginScreen overlay simultaneously
+- DashboardLayout is wrapped in DetailPanelProvider for both 'login' and 'pmr' phases
+- LoginScreen overlay: `fixed inset-0 z-50` with `rgba(240, 245, 244, 0.7)` + `backdrop-filter: blur(20px)`
+
+### Key Files for This Feature
+- src/App.tsx — phase management, will need restructuring for blur overlay
+- src/components/LoginScreen.tsx — main login screen (416 lines)
+- src/components/TopBar.tsx — Home icon replacement target (line 57)
+- src/components/DashboardLayout.tsx — rendered behind login blur
+- src/contexts/DetailPanelContext.tsx — wraps DashboardLayout
+- cvmis-logo.svg — source SVG with 3 capsule groups
+- LogoReveal/frame 1-5.jpg — animation reference frames
+
+### CvmisLogo Component
+- `size` prop: numeric, sets SVG height attribute directly
+- `cssHeight` prop: string, sets height via CSS style (use for clamp/responsive values)
+- `animated` prop: boolean, enables framer-motion reveal animation (1000ms total)
+- Logo animation: 500ms rise (green capsule) + 500ms fan-out (all three) = 1000ms total
+
+### LoginScreen.tsx Key Lines (post US-007)
+- Line 20: connectionState useState
+- Line 21: dotCount useState (for animated trailing dots)
+- Line 43: canLogin derived state
+- Line 60-101: startLoginSequence (typing animation)
+- Line 110-115: useEffect — connection transitions to green 500ms after typingComplete
+- Line 118-126: useEffect — animated dot cycling (500ms interval) while connecting
+- Line 128-150: useEffect — cursor blink + startLoginSequence delay (no more connectionTimeout)
+- Line 370-405: Connection status indicator (10px LED dot with glow, 12px text)
+
+---
+
+## 2026-02-15 - US-010
+- Reverted initial Phase state from 'login' back to 'boot' in App.tsx line 47
+- Full flow verified: boot → ECG → login (with blur, logo, typing, connection indicator, pulse) → dissolve → dashboard
+- Files changed: src/App.tsx
+- **Learnings for future iterations:**
+  - Simple one-line revert as planned in US-001
+  - The full boot→ECG→login sequence takes ~20 seconds before login screen appears
+---
+
+## 2026-02-15 - US-009
+- Changed outer overlay container from plain `<div>` to `<motion.div>` for animated exit
+- On isExiting: overlay animates backgroundColor to transparent, backdropFilter from blur(20px) to blur(0px) over 600ms
+- Card exit animation extended from 200ms to 400ms for smoother dissolve feel
+- onComplete callback fires after 600ms dissolve (previously 200ms card exit)
+- After dissolve completes, overlay removed from DOM and dashboard becomes interactive
+- prefers-reduced-motion: instant transition (0ms for all timers)
+- Files changed: src/components/LoginScreen.tsx
+- Verified in browser: clicked login → spinner → card fades + overlay blur dissolves → dashboard revealed
+- **Learnings for future iterations:**
+  - framer-motion can animate backdropFilter and backgroundColor on a motion.div via the animate prop
+  - The onComplete timeout (600ms) must match the overlay dissolve duration, not the card fade duration
+  - Card fade (400ms) finishes before overlay dissolve (600ms), creating a layered reveal effect
+  - WebkitBackdropFilter needs to be animated alongside backdropFilter for Safari
+---
+
+## 2026-02-15 - US-008
+- Added @keyframes login-pulse in index.css: scale 1→1.03→1 over 3s cycle (1.5s animation built into keyframe percentages with 1.5s pause)
+- Added .login-pulse-active class that applies the animation infinitely
+- Hover removes animation via CSS rule (.login-pulse-active:hover { animation: none })
+- Button gets login-pulse-active class when canLogin && !buttonPressed
+- prefers-reduced-motion: .login-pulse-active { animation: none } in reduced motion media query
+- Button opacity 0.6→1.0 transition preserved (existing behavior)
+- Button still receives keyboard focus when enabled (existing behavior)
+- Files changed: src/index.css, src/components/LoginScreen.tsx
+- Verified in browser: button has login-pulse animation running (3s ease-in-out infinite), class applied correctly
+- **Learnings for future iterations:**
+  - Used keyframe percentages (0%,60%,100% at scale(1), 30% at scale(1.03)) to build pause into a single animation rather than animation-delay
+  - CSS handles hover removal — no need for buttonHovered state in the class condition
+  - buttonPressed removes the class entirely (not just pauses), which is cleaner
+---
+
+## 2026-02-15 - US-007
+- Reworked connection status indicator: LED dot 6px→10px with glow box-shadow, text 10px→12px
+- Removed independent 2000ms connectionTimeout timer
+- Added useEffect that transitions to green 500ms after typingComplete becomes true
+- Added animated trailing dots cycling '.', '..', '...' every 500ms while connecting
+- Initial state: red LED + red text "Awaiting secure connection" with animated dots
+- Connected state: green LED + green text "Secure connection established, awaiting login"
+- 300ms smooth transition for color and box-shadow between states
+- prefers-reduced-motion: no dot cycling, instant state changes
+- Files changed: src/components/LoginScreen.tsx
+- Verified in browser: red indicator with cycling dots visible during typing, transitions to green after typing completes
+- **Learnings for future iterations:**
+  - dotCount state cycles 0→1→2→3→0 (4 states: no dots, '.', '..', '...') via modulo arithmetic
+  - Connection transition is now tied to typingComplete state, not an arbitrary timer
+  - The dot interval cleanup needs to happen in both the dedicated useEffect and the main cleanup
+  - LED glow uses rgba with 0.4 alpha for subtle effect matching project shadow conventions
+---
+
+## 2026-02-15 - US-006
+- Rendered DashboardLayout (wrapped in DetailPanelProvider) behind LoginScreen during login phase in App.tsx
+- Changed LoginScreen overlay from solid #1A2B2A background to semi-transparent rgba(240, 245, 244, 0.7) with backdrop-filter: blur(20px)
+- Dashboard is non-interactive during login (overlay captures pointer events via fixed inset-0 z-50)
+- After login click, phase transitions to 'pmr' and overlay is removed from DOM, dashboard becomes interactive
+- Files changed: src/App.tsx, src/components/LoginScreen.tsx
+- Verified in browser: blur overlay shows dashboard content behind login card, login click transitions to interactive dashboard
+- **Learnings for future iterations:**
+  - App.tsx phase rendering changed from exclusive (one phase at a time) to overlapping (login + pmr render DashboardLayout)
+  - DetailPanelProvider now wraps DashboardLayout for both 'login' and 'pmr' phases — condition is `(phase === 'login' || phase === 'pmr')`
+  - LoginScreen already had `fixed inset-0 z-50` which makes it a full-viewport overlay — just needed background/blur changes
+  - WebkitBackdropFilter needed for Safari compatibility alongside backdropFilter
+---
+
+## 2026-02-15 - US-005
+- Replaced Home icon with CvmisLogo (size={24}, static/no animation) in TopBar.tsx
+- Removed Home from lucide-react import (Search still used)
+- Imported CvmisLogo component
+- Files changed: src/components/TopBar.tsx
+- Verified in browser: logo renders correctly with teal/amber/green capsule colors, fits TopBar height
+- **Learnings for future iterations:**
+  - TopBar uses inline styles throughout, consistent with LoginScreen pattern
+  - Search is the only remaining lucide-react icon in TopBar.tsx
+  - CvmisLogo default `animated=false` means no animation prop needed for static usage
+---
+
+## 2026-02-15 - US-004
+- Rebranded login from "CareerRecord PMR" to "CVMIS" with subtitle "CV Management Information System"
+- Replaced Shield icon with CvmisLogo component (animated=true, responsive cssHeight)
+- Added `cssHeight` prop to CvmisLogo for CSS clamp-based responsive sizing: clamp(48px, 4vw, 64px)
+- Increased startLoginSequence delay from 400ms to 1500ms to let logo animation complete before typing begins
+- prefers-reduced-motion: keeps original 400ms delay since logo renders instantly
+- Fixed lint warning: added prefersReducedMotion to useEffect dependency array
+- Files changed: src/components/LoginScreen.tsx, src/components/CvmisLogo.tsx
+- **Learnings for future iterations:**
+  - CvmisLogo `size` prop is numeric (SVG height attribute) — use `cssHeight` string prop for CSS clamp values
+  - Logo animation is 1000ms total (500ms rise + 500ms fan-out) — typing delay must account for this
+  - The committed LoginScreen from US-003 still had Shield icon — US-003 only committed responsive sizing, not branding changes
+---
+
+## 2026-02-15 - US-003
+- Responsive card: width clamp(320px,28vw,480px), maxWidth calc(100vw-32px), padding clamp(24px,2.5vw,40px)
+- Replaced hardcoded colors with CSS variables: --surface, --bg-dashboard, --accent, --text-secondary, --text-tertiary
+- Input fields: #E4EDEB default border, var(--accent) focus border, var(--bg-dashboard) inactive bg
+- Font sizes: labels clamp(12px,1vw,14px), inputs clamp(13px,1.1vw,15px), button clamp(14px,1.1vw,16px)
+- Card shadow: 0 1px 2px rgba(26,43,42,0.05) matching project shadow tokens
+- Files changed: src/components/LoginScreen.tsx
+- **Learnings for future iterations:**
+  - No --border-card CSS variable exists in index.css — use #E4EDEB directly
+  - LoginScreen uses inline styles throughout, not Tailwind classes (except for focus-visible ring on button)
+  - The card used className="bg-white" which needed to be replaced with inline style for consistency
+---
+
+## 2026-02-15 - US-002
+- Created CvmisLogo.tsx component with inlined SVG paths from cvmis-logo.svg
+- Three capsule groups: capsule-rx (teal #0b7979), capsule-terminal (amber #d97706), capsule-data (green #059669)
+- Props: size (height px), animated (boolean, default false), className (optional)
+- Framer Motion animation: Phase 1 (rise 500ms) — green data capsule scales from 0, Phase 2 (fan-out 500ms) — all three appear
+- prefers-reduced-motion: skips animation, renders final state immediately
+- Files changed: src/components/CvmisLogo.tsx (new)
+- **Learnings for future iterations:**
+  - The SVG uses viewBox="0 0 600 506" with internal g transform scale(0.05,-0.05) — keep this coordinate system intact
+  - framer-motion's useReducedMotion() hook is the simplest way to handle reduced motion
+  - transform-origin in SVG needs px units when using framer-motion on g elements
+---
+
+## 2026-02-15 - US-001
+- Changed initial Phase state from 'boot' to 'login' in App.tsx line 47
+- Files changed: src/App.tsx
+- **Learnings for future iterations:**
+  - Phase state is a simple string union type on line 47 of App.tsx
+  - US-010 will revert this exact change back to 'boot'
