Schema-level invariants enforce that endsAt is null exactly when
endPrecision is "unknown", and that regionEnds is populated exactly when
regionScoped is set, so an event object cannot be constructed in a state
the UI would misrender.
Event IDs double as localStorage keys on the client, so slugify() and
eventId() carry a warning: changing them orphans every user's completion
marks with no server-side recovery.

Bun is the runtime, bundler, test runner and SQLite driver, so zod is the
only dependency. Strict TS with noUncheckedIndexedAccess.
