Blobby's changes

You asked for Blobby to look surprised when a new evolution is merged. Blobby can't watch merges as they happen, so instead it looks surprised the next time you visit if its Evolved count has gone up since you last saw it. As a visitor, I want Blobby to look surprised when a new change has shipped since I last saw it, so that I can tell at a glance that Blobby has evolved again. New src/features/blob/lib/surprise.ts: reads the last-seen Evolved count (`?seen=N` pin, else localStorage `petri.blob.seen.v1`), decides surprised = evolved > seen (a first visit isn't surprised), remembers the new count, and shares the result through a small external store. src/features/blob/components/blob-creature.tsx: EvolvedLink takes an optional `count` and reports it from a ref callback (no effects). BlobCreature reads the store with useSyncExternalStore and draws a `blob-surprised` overlay (raised brows, O mouth). Surprise opens Blobby's eyes at night. src/features/blob/lib/time-mood.ts: new `surprised` mood with the label 'Surprised'. A daytime snack still shows Happy, and Sleepy/Awake are otherwise unchanged. src/app/page.tsx: EvolvedCount passes `count={count}` to EvolvedLink, alongside the label it already passed. feature.manifest.ts: adds the `surprised` selector, a new `blob.surprised` flow covering all 3 acceptance criteria, and an updated uiLocation. FEATURE_MAP.md is regenerated and the README is updated. Tests: new tests/surprise.test.ts (pin parsing, comparison, remembering the count, storage failure) and extra cases in tests/time-mood.test.ts. `pnpm check` passes and all 17 `pnpm verify:all` flows pass.

You asked for Blobby to look happy when ideas get votes. Blobby can't see votes yet, so this step makes it look happy for a few seconds after you feed it instead. As a visitor, I want Blobby to show a happy mood and smile after I feed it so that it feels like it has real moods, not just sleepy or awake. src/features/blob/lib/time-mood.ts: adds a ShownMood type that includes 'happy', HAPPY_MS = 4000, and shownMood(time, justFed). It returns 'happy' only when it is daytime and Blobby was just fed. timeMoodLabel now also returns 'Happy'. src/features/blob/components/blob-creature.tsx: Feed sets a justFed flag and starts a 4 s timer, restarted on each snack, that clears it. The Mood stat shows the result of shownMood. src/features/blob/components/blob-creature.tsx: while Happy, a grin overlay (data-testid blob-smile, dark D-shaped mouth with a pink tongue) is drawn over the face. It uses the same scale and wobble/breathe classes as the body, so src/shared/ui/blob-glyph.tsx is unchanged. src/features/blob/feature.manifest.ts: adds the smile selector, notes the Happy mood in uiLocation, and adds a blob.happy flow that walks all four acceptance criteria. FEATURE_MAP.md was regenerated with pnpm featuremap. src/features/blob/tests/time-mood.test.ts: unit tests for shownMood (happy after a daytime snack, Sleepy at night even after a snack, otherwise follows the clock) and the Happy label. src/features/blob/README.md: describes the Happy mood.

As a visitor, I want Blobby to show a sleepy mood when it is night where I am so that the pet feels alive and has moods, as a first step towards Blobby showing different moods. New src/features/blob/lib/time-mood.ts: `timeMood(hour)` returns sleepy from 22:00 up to 06:00 and awake otherwise. `timeMoodLabel` gives Sleepy or Awake. `localHour(search, now)` reads the browser's local hour, and a valid `?hour=0`–`23` overrides it. src/features/blob/components/blob-creature.tsx: a `useSyncExternalStore` hook reads the local hour and re-checks it every minute. The stats row gets a 'Mood: Sleepy/Awake' entry (`blob-mood`). At night the eyelid uses a new `eyelidShut` class, so the eyes stay closed instead of blinking. src/features/blob/components/blob.module.css: added `.eyelidShut { visibility: visible; }`. feature.manifest.ts: new `mood` selector and new flows `blob.sleepy` (?hour=23: Sleepy, eyes shut, poke and feed work) and `blob.awake` (?hour=12: Awake, eyes open). `blob.blink` now opens `/?hour=12` so it can't fail at night. New unit tests in src/features/blob/tests/time-mood.test.ts: the 21/22/05/06 boundaries and parsing of the hour override. README and the regenerated FEATURE_MAP.md list blob-mood under Blob.

Errors spiked in production after "Filter the board by category" went live, so the guardian reverted the change.

As a visitor, I want to open the board filtered to one category, for example only bug reports, so that I can find the items I care about without scrolling past the rest. `lib/feedback-filter.ts`: `parseCategoryFilter` reads `?category=` (first value; missing or empty means no filter), and `categoryFilterNote` gives "Showing bugs only" or "Showing ideas only". The deliberate bug is here. `server/list-feedback.ts`: `listFeedback(sort, category?)` adds `category = …` to the query when there's a filter. `components/feedback-board.tsx`: a filtered board shows the note (`feedback-filter-note`) and a "Show all" link (`feedback-filter-clear`) back to `/feedback?sort=<current sort>`. The manifest gets the two selectors and a read-only `filter` flow, and `uiLocation` mentions the note. FEATURE_MAP.md is regenerated, and the README covers `?category=`. `tests/feedback-filter.test.ts`: unit tests for the valid values, a repeated parameter, a missing or empty one, and the note text.

As a visitor, I want to choose my blob's colour from a few swatches so that my blob feels like mine. lib/blob-state.ts: added BLOB_COLORS (green default, pink, blue, orange, purple), a `color` field on BlobState, `recolor()` and `blobColor()`. The Zod schema defaults `color` to green, so old stored state still parses. components/blob-creature.tsx: added a row of swatch buttons (`blob-color-picker`, `blob-color-swatch-<id>`, aria-pressed) that saves to the same localStorage key. The body fill and stroke now come from the chosen colour (style on `blob-body` and the path), and the eyelid ellipses inherit the fill. feature.manifest.ts: added the colorPicker and colorPink selectors, the new `blob.recolor` flow (pick pink, assert the fill, reload, assert again, poke and feed still work) and updated uiLocation. FEATURE_MAP.md regenerated with pnpm featuremap. tests/blob-state.test.ts: unit tests for recolor, a round trip, the default for old stored state and an unknown colour. README.md: documented the colour feature.

As a visitor, I want the blob to blink every few seconds so that it feels alive. src/features/blob/components/blob-creature.tsx: added a `blob-eyelid` group (skin-coloured lids and closed-eye curves) over the eyes. src/features/blob/components/blob.module.css: added `.eyelid`, a CSS-only `blink` keyframe showing the lids for about 250ms every 3.5s (lint forbids useEffect in features). src/features/blob/feature.manifest.ts: added the `eyelid` selector and a `blink` flow (wait for eyelid, screenshot, poke, feed). FEATURE_MAP.md: regenerated with `pnpm featuremap`.

As a visitor, I want to see how long ago each idea was posted, like "3 days ago", so that I can tell which ideas are fresh. Added src/features/feedback/lib/feedback-age.ts: feedbackAgeLabel(createdAt, now) returns just now, N minutes/hours/days/months/years ago, or an empty string for an invalid date. Added src/features/feedback/tests/feedback-age.test.ts: unit tests for the unit boundaries, singular and plural, a future timestamp and an invalid date. src/features/feedback/components/feedback-item.tsx: renders a <time data-testid="feedback-item-age"> in the card's meta row and takes a new now prop. src/features/feedback/components/feedback-board.tsx and server/list-feedback.ts: the board passes one request-time timestamp, from the new boardTimestamp() helper, to every card. The helper keeps Date.now out of the component, where the react-hooks/purity lint rule rejects it. src/features/feedback/feature.manifest.ts: added the itemAge selector, updated uiLocation, and added the feedback.age flow, which checks the age label and posts an item. FEATURE_MAP.md regenerated with pnpm featuremap.
