Marcos Paulo 48c31dc1b3 build: migrate from npm to pnpm
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.

# Task 15 — Full guide
**Agent**: `page-migrator` · **Model**: **Codex** — hardest task in the plan
**Depends on**: 05, 10, 13 · **Parallel with**: 16 **Worktree**:
`.agents/scripts/worktree.sh start 15 page-full-guide`
## Goal
`/full-guide/` → Astro. 22 KB of HTML, a 50 KB script, 30 KB of CSS, twelve
render functions, bilingual throughout.
## What `app.js` actually is
Not application code — a **bilingual content database** (task 05 already moved
it) plus ~12 `render*` functions that swap `innerHTML` on tab clicks. Once
content is a collection, the remaining JS is small: tab state and a language
toggle.
## Islands
Only these hydrate. Everything else is server-rendered.
| Island | Directive | Why |
| -------------------------------------------------------- | ---------------- | -------------------------------------------------- |
| Phase tabs | `client:visible` | click-driven panel swap |
| Tree / worker / route / model / effort / skill selectors | `client:visible` | same pattern; consider one generic selector island |
| Language toggle | `client:idle` | page-wide, not urgent |
| Copy-prompt buttons | `client:visible` | clipboard |
If you end up with 12 separate islands you have missed the pattern — they are
one selector component with different data.
## Asserted by verify.mjs — all must survive
`const phases`, `const handsOnPrompts`, `const modelGuide`,
`const skillSources`, `const skillInstallPrompts`, `render('plan')`,
`renderTree`, `renderWorker`, `renderRoute`, `renderModelProvider`,
`renderEffort`, `renderSkillFile`, `renderSkillWorkflow`, `renderCommonSkill`,
`renderHandsOn`, `copyPrompt`.
These are **implementation-detail assertions** — they look deletable and are
not. Each pins a feature. Coordinate with task 19 to replace each with an
output-level assertion of the same behaviour. **Never delete one yourself.**
Also: `data-copy-target="prompt-install-skills|prompt-basic|prompt-skills"`,
`hands-on/starter/`, `additional-reading.md`, `role="tablist"`, `<table>`.
## Watch for
- `copyPrompt` uses `navigator.clipboard` with a `document.execCommand`
fallback. Keep both — the fallback exists for non-secure contexts.
- The hands-on prompt strings are copy-pasted by attendees into an agent. Exact
whitespace and line breaks matter.
- `responsive.css` (30 KB) mostly serves this page. Port what is needed, prove
the rest dead, delete it. Screenshots are the proof.
## Done when
- [ ] Snapshot diff empty
- [ ] Every interaction works: all tabs, both languages, all copy buttons
- [ ] Keyboard: arrow keys move between tabs; focus visible throughout
- [ ] JS payload **smaller** than today's 50 KB (content is now static)
- [ ] Screenshots match at four widths; checklist complete; `pnpm run gate`
