feat(web): Vue 3 SPA scaffold with avocet lessons applied
Sets up web/ Vue 3 SPA skeleton for issue #8, synthesizing all 15 gotchas
from avocet's Vue port testbed. Key fixes baked in before any component work:
- App.vue root uses .app-root class (not id="app") — gotcha #1
- overflow-x: clip on html (not hidden) — gotcha #3
- UnoCSS presetAttributify with prefixedOnly: true — gotcha #4
- peregrine.css alias map for theme variable names — gotcha #5
- useHaptics guards navigator.vibrate — gotcha #9
- Pinia setup store pattern documented — gotcha #10
- test-setup.ts stubs matchMedia, vibrate, ResizeObserver — gotcha #12
- min-height: 100dvh throughout — gotcha #13
Includes:
- All 7 Peregrine views as stubs (ready to port from Streamlit)
- AppNav with all routes
- useApi (fetch + SSE), useMotion, useHaptics, useEasterEgg composables
- Konami hacker mode easter egg + confetti + cursor trail
- docs/vue-spa-migration.md: full migration guide + implementation order
- Build verified clean (0 errors)
- .gitleaks.toml: allowlist web/package-lock.json (sha512 integrity hashes)
