# 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-004)
- Line 20: connectionState useState
- Line 43: canLogin derived state
- Line 60-101: startLoginSequence (typing animation)
- Line 110-139: useEffect with connectionTimeout (2000ms) and startLoginSequence delay (1500ms / 400ms reduced motion)
- Line 145-409: JSX render (card, form, button, status indicator)
- Line 208-211: CvmisLogo with cssHeight="clamp(48px, 4vw, 64px)" animated=true
- Line 221: "CVMIS" title
- Line 232: "CV Management Information System" subtitle
- Line 350-382: Connection status indicator (6px dot, 10px text)

## 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'
