 - [x] **Task 3: Rebuild LoginScreen.** Read `Ralph/refs/ref-transition-login.md`. Key changes from prior version: (a) Typing speed is now **80ms/char** for username, **60ms/dot** for password — natural pace, not frantic. (b) After typing completes, the "Log In" button becomes **user-interactive** — the user clicks it to proceed. It is NOT auto-triggered. Button should have hover state, full opacity when ready, disabled/dimmed while typing. (c) Card shadow uses multi-layered shadow per design system. (d) Uses [UI font] for labels, Geist Mono for input fields. (e) `prefers-reduced-motion`: typing completes instantly, button is immediately interactive.

Condensed banner (48px) via IntersectionObserver at 100px scroll. Mobile minimal banner with overflow menu. Uses [UI font] throughout. NHS Number tooltip: "GPhC Registration Number".

CV-friendly labels: Summary, Experience, Skills, Achievements, Projects, Education, Contact. 220px fixed width. Header branding, search input, navigation items with exact states (default/hover/active), separator line, footer with session info. Tablet mode: 56px icon-only. Keyboard shortcuts: Alt+1-7, arrow keys, "/" for search. URL hash routing.

 **Next task:** Task 4 — Rebuild PatientBanner
 
+## Iteration 4 (Task 4: Rebuild PatientBanner)
+
+**Task completed:** Task 4 — Rebuild PatientBanner with premium fonts, tooltip, animations
+
+**Changes made:**
+- Rebuilt `src/components/PatientBanner.tsx`:
+  - Replaced all `font-inter` references with `font-ui` (Elvaro Grotesque)
+  - Added `NHSNumberWithTooltip` component — custom styled tooltip with Framer Motion, 300ms hover delay, arrow indicator (replaces native `title` attribute)
+  - Added `AnimatePresence` for smooth crossfade between full/condensed banner states
+  - Mobile overflow menu now uses `AnimatePresence` for animated enter/exit
+  - Replaced fixed backdrop click handler with `useRef` + `useCallback` + document event listener pattern (click-outside)
+  - Mobile banner now uses `patient.nhsNumber` and `patient.status` data instead of hardcoded values
+  - DOB value rendered in `font-geist` (monospace) for clinical data texture
+  - Badge changed from `rounded-sm` to `rounded-full` (pill shape)
+  - Added `shadow-pmr-banner` drop shadow to header
+  - Added focus ring styles on action buttons (`focus:ring-2 focus:ring-pmr-nhsblue/40`)
+  - `prefers-reduced-motion` support for banner crossfade
+- Added `SkipButton` component to `src/App.tsx` — appears after 1.5s during boot/ECG phases, skips to login
+
+**Quality checks:** All passed (typecheck, lint, build — 394.81 KB bundle)
+
+**Visual review:** Completed via Playwright MCP. Banner renders correctly with premium font, NHS blue action buttons, shadow, monospace NHS number, status dot with text label.
+
+**Known issue (pre-existing):** Banner sentinel element has `absolute top-0` positioning inside a non-positioned parent, causing the IntersectionObserver to always report "not intersecting" — banner shows condensed state even at scroll position 0. The full 3-row banner (with DOB, address, phone, email) never displays. This is NOT a regression from Task 4 — the sentinel placement was unchanged. Should be addressed in a future task.
+
+**Codebase patterns discovered:**
+- `AnimatePresence mode="wait"` is the right pattern for crossfading between two states (full/condensed banner)
+- Custom tooltip with Framer Motion + `onMouseEnter`/`onMouseLeave` with 300ms delay is more styleable than native `title`
+- Click-outside pattern: `useRef` on container + `useCallback` for handler + `useEffect` to add/remove document listener
+
+## Manual Intervention — 2025-02-12
+### Reason: Replaced Claude in Chrome browser integration with Playwright MCP for visual validation
+### Changes made:
+- `RALPH_PROMPT.md`: Updated visual review step (step 7) to use Playwright MCP tools (`mcp__playwright__browser_navigate`, `mcp__playwright__browser_take_screenshot`, `mcp__playwright__browser_snapshot`, `mcp__playwright__browser_wait_for`) instead of Chrome extension tools (`tabs_context_mcp`, `computer` screenshot)
+- `guardrails.md`: Updated visual review guardrail to reference Playwright MCP tools
+- `progress.txt`: Updated "Visual Review" codebase pattern section with Playwright MCP tool names
+- `ralph.ps1`: Updated comments referencing Chrome to reference Playwright MCP
+### Tasks reset: None
+### Tasks added: None
+### Context for next iteration:
+- Visual review is now done via **Playwright MCP** tools, NOT Claude in Chrome
+- Key tools: `mcp__playwright__browser_navigate` (go to URL), `mcp__playwright__browser_take_screenshot` (visual capture), `mcp__playwright__browser_snapshot` (accessibility tree), `mcp__playwright__browser_wait_for` (wait for time/text)
+- The dev server still runs on `http://localhost:5173` — workflow is the same, just different tool names
+- Previous iterations skipped visual review because Chrome tools weren't available — Playwright MCP should now work
+### New guardrails added: None
