369-374: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winThe spinner ignores reduced motion.
animate-spinkeeps rotating when the visitor prefers reduced motion. The progress bar on Line 341 already usesmotion-reduce:transition-none, so the panel is inconsistent.♻️ Proposed fix

In `@src/components/landing/QueryLanding.tsx`:
- Around line 261-264: Update the fetchedLabel logic in QueryLanding so the
elapsed-time display refreshes periodically while the panel is mounted, using a
ticking state or equivalent timer-driven value instead of calling Date.now()
only during unrelated renders; preserve the existing “primed” fallback and
seconds formatting.
- Around line 266-270: Update the React.useEffect controlling isLive in
QueryLanding so it handles both preference states: enable live updates when
prefersReducedMotion is false and disable them when it is true, preserving the
dependency on prefersReducedMotion so changes stop the refetch loop.

The Query landing's hero panel stopped working: toggling Live on only swapped the label (
fresh⇄paused) and Add issue just cycled the selected row. The progress bars (92% / 78% / 68%) and stats (success / false / 3,200 / idle) never changed, because they are hardcoded config values.Where it comes from
LibraryLanding.tsxwas introduced by #1027, which replaced the copy-pasted per-library landings with one config-driven template. Query's hero had been a working demo before that —git show ce725bd6^:src/components/landing/QueryLanding.tsxshowsuseQuery+useMutationwith optimistic updates. Collapsing it into static config dropped the behaviour;QueryLanding.tsxwent from 798 lines to 119.What this does
Adds an optional
heroRendertoLibraryLandingConfig, so a landing can supply its own hero while keeping the shared feature/lifecycle/flow sections:Query passes a
QueryCachePanelthat runs a realQueryClient: the cache badge, revision counter, and rows are derived from query state, and Add issue is an optimistic mutation that rolls back on error. Only Query opts in — every other landing keeps the mockup.The logic is ported from the pre-#1027 panel; the markup is rewritten against the current design tokens (
--landing-accent,text-ds-*,font-ds-mono) rather than the pre-rebrand classes, and the icons use phosphor.Verified in the browser
Live toggle now controls refetching —
fetchedAtlabel sampled every 700ms:3s → 3s → 3s …(12 samples, never refreshes)33s → 38s → 0s → 0s …(reset = refetch fired)Add issue is a real mutation — rows 4 → 5,
rev 1 → 2, mutation statussuccess → pending → success, with the optimistic row appearing ~300ms before the server settles.tsc,oxlintand the 128 unit tests pass.Summary by CodeRabbit
