## Summary

- Replace the single root `favicon.ico` with a complete asset bundle under [`apps/portal-shell/public/favicons/`](apps/portal-shell/public/favicons/): SVG primary favicon, PNG fallback (96×96), legacy ICO, Apple touch icon (180×180), and a Web App Manifest with 192 / 512 maskable PNGs.
- Wire the assets in [`index.html`](apps/portal-shell/src/index.html) via the standard `<link rel="icon|apple-touch-icon|manifest">` block and add a matching `<meta name="theme-color" content="#ffffff">`.
- Set the manifest name to `"APF Portal"` (short_name `"Portal"`) so the PWA install banner and home-screen icon read consistently with the in-app header.

## Why it matters

- **Modern favicons.** SVG is now the primary icon — vector-clean at every density, automatic dark-mode adaptation when the SVG carries `prefers-color-scheme` rules. PNG + ICO entries cover legacy and pinned-tab contexts.
- **Installability.** With a valid manifest + 192/512 icons + `display: standalone`, the portal is installable on Android home-screens and as a desktop PWA in Chromium-based browsers, without shipping a service worker.
- **Mobile chrome.** `<meta name="theme-color">` aligned with the manifest's `theme_color` tints the browser address bar and the PWA chrome to white — matching the app header.

## Decisions worth flagging

- **Icons declared `purpose: "maskable"` only.** The PNGs were generated with the Android safe-zone padding. On Android they render correctly (cropped to the device's adaptive shape); on contexts that ask for `"any"` the browser falls back to the SVG / PNG / ICO entries from the `<link rel="icon">` block, so nothing breaks. If we later want a no-padding edge-to-edge variant for desktop, we can add a second icon entry with `purpose: "any"` and a different source.
- **`theme_color: #ffffff` rather than brand teal.** The app header is white in the v1 design; tinting the mobile chrome to teal would create a visible seam at the top of the viewport. We can revisit if a darker header lands.
- **Cache-buster query strings kept (`?v=20260511`).** Static `public/` assets are not hashed by Angular's build (only bundled JS/CSS are), so the explicit version stamp guards against stale caches on icon updates. The date matches the generation day.

## What this PR explicitly does NOT do

- Ship a service worker / offline support (PWA installability does not require it; offline strategy is a separate decision and likely a future ADR).
- Replace the SVG icon contents with a brand-tuned design — uses the existing generator output.
- Wire a localized manifest (single `name` / `short_name`, no `lang` variant per locale).

## Test plan

- [x] `pnpm exec nx build portal-shell --configuration=production` — green, 100 kB gzip initial (unchanged).
- [x] All 7 assets ship to `dist/apps/portal-shell/browser/favicons/`.
- [x] `index.html` in the production build contains every `<link>` + the `theme-color` meta.
- [ ] Manual: tab favicon visible in Chrome / Firefox / Safari.
- [ ] Manual: Chrome DevTools → Application → Manifest reports no errors and shows both 192/512 icons.
- [ ] Manual: Chrome desktop install prompt offers "Install APF Portal".
- [ ] Manual: Add-to-Home-Screen on Android shows the maskable icon clipped to the device's adaptive shape.

Julien Gautier bea5e1954f chore: generate portal-shell and portal-bff apps per ADR-0004 / ADR-0005
Add the @nx/angular, @nx/nest, @nx/vite, @nx/eslint plugins, then
generate the two apps. Adjust the empty-template tsconfig.base.json
to be Angular-compatible (drop project references and customConditions
that the empty-template defaults to but Angular doesn't support; keep
the strict-TS extensions from ADR-0004).

apps/portal-shell (Angular 21):
- standalone APIs, routing, SCSS, esbuild
- vitest-angular as unitTestRunner, playwright for e2e
- strict mode
- tags scope:portal-shell, type:app
- app.config.ts wired with provideZonelessChangeDetection() per
  ADR-0004 (Angular 21 + Nx 22 generates without zone.js by default)

apps/portal-bff (NestJS 11):
- Express adapter (default per ADR-0005)
- Jest as unitTestRunner
- tags scope:portal-bff, type:app
- main.ts wired with a global ValidationPipe configured
  whitelist + forbidNonWhitelisted + transform per ADR-0005
- Phase-2 security additions (helmet, CORS, sessions, CSRF, rate
  limit, auth guards, error filter) deferred to their respective
  ADRs - placeholder comment in main.ts

Workspace dependencies: class-validator + class-transformer added
(required by NestJS ValidationPipe at runtime). Nx-generated
.gitignore additions (.angular, __screenshots__) merged into ours.
.vscode/extensions.json and launch.json added by Nx are kept (do not
override our existing settings.json).
