**Verified:** `typecheck` + `test` (61 passing, incl. `vega-themes.test.ts`) +
`build` (Plex woff2, all script subsets, bundled & precached via the PWA
`globPatterns`). Both themes screenshotted via the real
app (chrome + Monaco + chart all repaint on theme flip); focus ring visible.
Notes from the build-out: the placeholder `'experimental'` theme was renamed to
`'dark'` (the settled name); the swappable `[data-accent]` layer landed with
indigo as the robust default (no switcher UI until M5); Monaco's `fontFamily` is
set to Plex Mono explicitly since it can't read the CSS token.

### Theme flow (end to end)
Theme spans several layers; the path is:
`AppStore.uiTheme` (+ `toggleTheme`) → `orchestration/theme.ts` mirrors it onto
`<html data-theme>` and writes through to `infrastructure/settings-store.ts`
(localStorage `ui.theme`). On load, `initTheme()` — called from `main.tsx`
**before** `createRoot().render` — hydrates the saved theme. Chart and editor
follow by subscribing to `uiTheme`: `LivePreview` re-embeds with
`chartConfigFor(theme)`, `SpecEditor` sets the Monaco theme. UI chrome repaints
purely from the `[data-theme]` token swap in `styles/tokens.css`. The header
`ThemeToggle` is the user control.
- **Do** hydrate the theme **synchronously before first paint** — an async
hydrate (e.g. inside `initApp`) flashes the default theme on load.
- **Do** keep the store browser-free: the `data-theme` write and the localStorage
write-through live in `orchestration/theme.ts`, never in the store or a component.
- The control currently lives in the header; spec §07 houses it in the Settings
modal (M5), which will share the same `ui.theme` key.
