* feat(devex): component fixtures with headless screenshots for fast UI checks
Colocated *.fixture.tsx files export named fixtures (render + optional store
seed, setup, interact, width). A dev-only Vite entry (vite.fixtures.config.ts,
extending vite.web.config.ts) renders one fixture in isolation with the real
I18nProvider, TooltipProvider, theme class, default-seeded store, and the web
client's preload bridge (installWebPreloadApi) as window.api.
`pnpm fixtures:shot <id|glob> [--theme dark|light|both]` starts or reuses a
detached server (Vite + one headless Chromium) and writes PNGs to
.cache/fixtures/. A warm page re-renders in place (~100ms/shot) and reloads
only after source changes. A stdio MCP server (registered in .mcp.json)
exposes list_fixtures and screenshot_fixture.
Fixtures load only through import.meta.glob in the fixture entry, which is
not a production build input; oxlint rejects static imports of *.fixture.
* Keep fixture config and agent config inside reviewed root entries
* Baseline the fixture page's default-settings seed in the focus-read ratchet
* docs(agents): shorten fixtures pointer
* Allowlist the dev-only fixture explorer's labels in localization coverage
