Squeek Pet v2: polish the existing game in this repository. Keep the stack (Vite + TypeScript), the file layout, the save key squeek-pet:v1 and every existing rule unless a change below says otherwise. Old saves must keep loading: add new save fields as optional with defaults in parseSave. Rebuild and commit dist/ as before.

1. BUG: festival on first visit Seen on the live site: a new player adopted a hamster at 08:05 UTC and a 2x festival started immediately, although the newest qualifying event (measurement.distance_milestone, occurredAt 04:04:30Z) was 4 hours old. processEvents is meant to count only events from the last hour on the first fetch. Find the path that lets an old event through (adopt flow calls applyEvents(lastEvents, Date.now()) in src/main.ts; check processEvents in src/logic.ts, the save passed in, and any event fetched before adoption). Fix it and add a unit test reproducing exactly this case: fresh save, events all older than 1 hour, no festival. Also: a newly adopted pet must never get a festival from an event that happened before its bornAt.

2. Squeektoshi's records card (data already parsed) On Home, under the live strip, add a compact "Squeektoshi's records" card from /measurement/stats?range=7d records: top speed (km/h, from peakObservedSpeedMmPerSecond x 0.0036), longest Squeek day (km, maximumDailyDistanceMm / 1e6), peak rpm (peakObservedRpmMilli / 1000), most passes in 30 minutes (mostWorkHalfHour), with the date of each. Unknown values show "n/a". Also show "Last ran: X ago" in the live strip when the wheel is IDLE, computed from the latest 30-minute bucket with workUnits > 0 (reuse bucketStart).

3. Share card Add a "Share my hamster" button on Home that draws a 1200x630 PNG on a canvas: the pet in its current pose with equipped hat, wheel skin and background, its name, stage, Seeds earned in total (add a lifetime seedsEarned counter to the save), days together (from bornAt), the line "Runs in sync with Squeektoshi on Squeekchain" and the site address. Offer "Download image" (blob URL + a download link) and, where navigator.share with files is supported, "Share". No upload anywhere.

4. Vietnamese language Add an EN / VI switch in the header, saved in the save (default: browser language, vi* -> VI). Move every user-facing string, including toasts, quest titles, item names and notes, the About text and the away card, into one dictionary (src/i18n.ts) with English and Vietnamese. Vietnamese must be natural, not word-for-word. Numbers and dates use Intl with the chosen locale. Keep the html lang attribute in sync.

5. Recent milestones on Home Below the records card, list the 3 newest events from /events?category=measurement already fetched (speed records, distance milestones, daily distance milestones, distance streaks) as short lines with relative time, e.g. "Passed 40 km in total, 4 h ago", "New top speed 5.9 km/h". Use the payload fields thresholdDistanceMm, recordMmPerSecond, days, minimumDailyDistanceMm. Ignore unknown types.

6. Credits and links (About screen) Add a "Made by" line: "Made by @Truongsonxyz" linking to https://x.com/Truongsonxyz, and a "Join Squeekchain Genesis" link to https://squeekchain.com/genesis/e86n3z8y with one sentence: "Genesis is Squeekchain's community campaign before launch." Plus a link to the source repository. Plain links, no tracking parameters.

7. Small fixes

• Feed menu: show how many of each food are in the pantry and grey out foods you can't afford, with the price in words for screen readers.
• When the hourly Seed cap is reached, show the reset time ("more Seeds at 15:42") instead of only the toast.
• The away card must also appear when the 7-day log arrives later than the status call (check settleAway is reached in both orders) and must never be shown twice for the same away window.
• Respect prefers-reduced-motion for the confetti and the running animation (slow walk instead of spin).

DO NOT

Do not add a wallet, a backend, analytics, trackers, external fonts or images. Do not raise API poll rates (status 15 s, stats 5 min, events 2 min, only while visible). Do not change the economy numbers.

ACCEPTANCE

• npm run build and npm test pass; new unit tests cover: the festival first-visit case, a pet never getting a festival from events before bornAt, the last-ran calculation, seedsEarned accumulating from runs, away earnings and quests, and save migration (a v1 save without the new fields loads with defaults).
• Switching EN/VI changes every visible string on all screens with no leftovers, and persists after reload.
• Share card downloads a 1200x630 PNG that shows the equipped cosmetics.
• Records and milestones show live values from api.squeekchain.com, and "n/a" when blocked.
• No horizontal scroll at 320 px and 390 px; no console errors; dist/ rebuilt and committed; README updated (new features, i18n file, share card, save fields).
