Problem

Around midnight Europe/Berlin the Europa-Park waiting-times feed stops listing rides for the main park, Rulantica and Traumatica. It keeps only restaurants (all closed) and the virtual-queue entries. Rides reappear one by one before opening (from about 07:00 local). Overnight, about a third of the destination's live entities (151 to 102) disappeared from buildLiveData output instead of reading CLOSED. A consumer that treats a missing entity as removed loses those rides' live state every night.

Fix

src/parks/europapark/europapark.ts

• rememberRides() keeps the rides the feed listed in the last 7 days (entity id to last-seen time, cached under europapark:recentRideIds).
• _carryForwardAbsentRides() runs after the wait-time passes. While a ride's own park is outside its published hours, a remembered ride the feed no longer lists is emitted as {status: 'CLOSED'}.
  • Main park: live calendar (insideMainParkHours), falling back to the seasons feed.
  • Rulantica / Traumatica: seasons feed (insideSeasonHours), starting from yesterday so a closing time after midnight counts.
• Not changed:
  • a ride the feed does list keeps its reported status (the morning ramp's 222/333 entries win);
  • an absent ride inside published hours is still left out;
  • nothing is carried when a park's hours cannot be read;
  • a ride never listed is never invented, and one unlisted for over a week is forgotten.
• Runs before _applyMainParkClosure, so closed-day handling is unchanged.

Tests

__tests__/overnightRideDrop.test.ts replays the real 2026-09-28 fixtures with a night feed derived by removing every ride entry:

• every ride seen by day reads CLOSED overnight, across all three parks;
• morning ramp, own-hours per park (Rulantica open while the main park is closed), inside-hours absence, no memory, both hour sources failing, calendar fallback, 7-day expiry;
• pure tests for rememberRides, insideMainParkHours and insideSeasonHours.

With the carry-forward disabled, 4 of the new tests fail (the overnight, three-park, per-park-hours and calendar-fallback cases). Full suite: 4116 passed, 1 skipped. Typecheck clean.
