 Make app a PWA with offline support (#11) 
## Summary
- Add `@vite-pwa/sveltekit` for automatic service worker generation
(Workbox) and web manifest
- Generate 192px and 512px PNG icons from `favicon.svg` at build time
via a sharp-based Vite plugin
- Enable prerendering via `+layout.ts` so the PWA precache includes the
HTML shell
- Add apple-touch-icon and favicon links to `app.html`

## Test plan
- [x] `bun run build` completes with no warnings
- [x] `bun run check` passes
- [x] Built output includes `sw.js`, `manifest.webmanifest`,
`icon-192.png`, `icon-512.png`
- [x] App is installable as a PWA in Chrome/Safari
- [x] App works offline after initial load

Exam Timer

A single-page web app for displaying a countdown timer and instructions to students during an exam.

Features

  • Instructions pane — left side shows rendered Markdown; click anywhere to edit the source, press Escape or click "Done" to return to the preview
  • Timer pane — right side shows a large countdown; set the timer by entering either a duration (hours + minutes) or a specific end time
  • Color transitions as time runs low: amber → orange (< 10 min) → red with pulse (< 5 min) → "Time's Up"
  • Both the instructions and the timer end time persist in localStorage, so a page reload resumes where you left off
