Adds the two localStorage stores behind PRD F13 and joins their events to the
feed's in App, so they sort, filter, focus, expire and tick through exactly the
same code paths rather than a parallel set.
Three decisions worth naming:
- Export carries customGames and customEvents. These exist in one browser and
nowhere else — not in the feed, not on a server — so an export without them
would be a backup that loses the half the reader typed. Import merges by id
like every other set and never removes.
- A date is read in the reader's timezone, and a bare end date means the end of
that day. Someone who types 20 Aug means the 20th where they are; the feed's
00:00Z day boundaries are a parser declining to guess a time the source never
printed, which is a different situation from being told directly.
- An impossible date is refused rather than rolled over, because Date.parse
turns 30 February into 2 March and a silently shifted date is the failure this
product exists to prevent.
Deleting a game is refused while it still holds events, and deleting an event
leaves its marks and logged days alone — reaching into three stores on one tap
is how a misclick costs somebody a streak.

The data layer for PRD F13, with no UI and no behaviour change yet.
src/shared/custom.ts defines the two key spaces, their schemas, and the
projection into what the views read. Two properties are the point of it:
- A reader's event id is random, not derived from their title. They can type a
scraped event's exact name and date, which under ${game}:${slug}:${date} is a
byte-identical key — one completion mark and one streak silently shared by two
events. Randomness also means renaming their own event never moves its id.
- A reader's event carries no sourceUrl, so a hand-entered date can never be
attributed to a source, and claims no region split, because they entered one
instant and inventing three would fabricate two of them.
The rest is widening what was GameId-shaped into a lane that may be one of
theirs: clockFor takes the boundary fields structurally so their events run on
the identical countdown rather than a second one, day keys fall back to the
regional default for a lane with no server map, and gameMeta becomes a context
resolver so metaFor stays pure and total — a lane can outlive its game when an
import carries an event whose game did not come with it.
