Adds emulator-backed rules-unit tests verifying the Firestore rules
committed in Task 3, including the global constraint that
bookings/inquiries are never publicly readable. Excludes
firebase-tests/ from the default vitest run since it needs the
emulator (via `npm run test:rules`) rather than jsdom.
- Lazy-load Home in App.tsx so three/@react-three/fiber (~238 kB gzip) only ships to the
Home route, not to Shop/Book/Rules.
- Add max-width: 260px to ProductCard/ServiceCard so real images won't collapse Home/Book
grid layouts.
- Restore AnimatePresence mode="wait" in Book.tsx to eliminate the exit/enter double-stack
during step transitions, updating the three Book.test.tsx assertions that raced the
transition to findBy* queries.
- Hero3DScene: drop the meaningless "static" className string in favor of a dedicated
data-testid, add aria-hidden to the reduced-motion fallback branch, and remove the
unused @react-three/drei dependency (adding @types/three directly since it was only
present transitively via drei).
