Ten git worktrees each carried their own 225 MB node_modules (1.1 GB across five) and paid 11s per `npm ci`. pnpm hardlinks from a shared store: the same five worktrees cost ~250 MB total, and a fresh install is 4s. What changed beyond the mechanical rename: - `overrides` moved to `pnpm-workspace.yaml`. pnpm 11 does not read the `pnpm` field in package.json *or* npm's top-level `overrides`, and it fails silently — the vite/defu/language-server pins would have quietly stopped applying. - Build scripts are blocked by default in pnpm; esbuild and sharp are allowed explicitly via `allowBuilds` (renamed from `onlyBuiltDependencies` in 11). - `packageManager` + `engines` pin the toolchain. - gate.sh rejects a package-lock.json/yarn.lock/bun.lock outright, so an agent running `npm install` out of habit fails loudly instead of building a second, divergent dependency tree. - CI bootstraps pnpm with `npm install --global pnpm@11.25.0` rather than corepack (unbundled as of Node 25) or pnpm/action-setup (this self-hosted act-runner has never run a job; fetching a third-party action is not something to discover on the first one). Two pre-existing CI bugs fixed while in the file: - the gate installed with `npm install --package-lock=false`, which discarded the lockfile the previous session had just fixed. - the visual-regression step imported `playwright`, which is not a dependency, and `visual-regression.mjs` has no compare mode anyway — in CI it overwrote its own baselines and passed unconditionally. Removed with a comment; it comes back when it can diff. The `publish` job is now manual (`workflow_dispatch`). During the migration dist/ holds three HTML files against the live pages branch's ten, so publishing on every push to main would take the site down to a stub. Restore at task 20. HANDOVER.md's incident log still says npm where it describes what happened at the time; that is history, not a missed rename. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Task 18 — Motion pass
|
||
|
||
**Agent**: `motion-designer` · **Model**: Gemini (perceptual judgement)
|
||
**Depends on**: 15, 16 · **Parallel with**: 19 **Worktree**:
|
||
`.agents/scripts/worktree.sh start 18 motion`
|
||
|
||
## Goal
|
||
|
||
Audit the motion that exists, add only motion that earns its place, and make
|
||
`prefers-reduced-motion` correct everywhere.
|
||
|
||
## Order of work — audit first
|
||
|
||
The audit is worth more than the additions.
|
||
|
||
1. Inventory every `transition`, `animation`, `@keyframes`, `transform` in
|
||
`src/`.
|
||
2. Flag anything animating a layout property (`width`, `height`, `top`, `left`,
|
||
`margin`). Those force reflow every frame and fail the 200ms INP budget. The
|
||
Stylelint config already blocks new ones; find the ported ones.
|
||
3. Confirm every animated element has a reduced-motion path, then **test it**
|
||
under DevTools emulation. Reduced means reduced, not broken — end states must
|
||
still be correct.
|
||
|
||
## Then, sparingly
|
||
|
||
Candidates, each needing a written purpose:
|
||
|
||
- tab panel change in the guide (state change — justified)
|
||
- review-desk detail swap on selection (state change — justified)
|
||
- vote widget tally update (feedback — justified)
|
||
|
||
`transform` and `opacity` only. 150–250ms. `cubic-bezier(.2,0,0,1)`. One thing
|
||
moves at a time — no staggered card cascades; this design has a point of view
|
||
and staggering reads as a template.
|
||
|
||
## View transitions — optional, decide explicitly
|
||
|
||
Astro's `<ClientRouter />` is the only sanctioned motion dependency. If adopted,
|
||
verify: JS-disabled navigation, browser back/forward, the review desk's six
|
||
query params, and reduced motion. If any fails, do not ship it.
|
||
|
||
## Done when
|
||
|
||
- [ ] Zero animations on layout properties
|
||
- [ ] Every animation has a one-line written purpose
|
||
- [ ] Reduced-motion tested under emulation; end states correct
|
||
- [ ] Before/after captures attached; `pnpm run gate` green
