/* Page layout for the server-rendered documents (UI_PLAN.md §2.1, slice U9).
 *
 * What this file is: the layout of the shells the Worker renders — the app
 * shell (sidebar, bottom nav, content column, breadcrumbs), the settings
 * pages, the auth pages, the error page, and the appearance swatch grid. It
 * is loaded by all three documents (AppShell, AuthShell, and the SPA document
 * in src/views/app-shell.tsx), which is why the shell chrome here is shared
 * with src/client/app/App.vue: both draw the same classes.
 *
 * What this file is NOT: a control stylesheet. Every button, chip, field,
 * list row, card, tile and avatar on these pages is a component class from
 * src/client/ui/ui.css (`ui-*`), which ships inside public/dist/islands.css
 * and is linked by all three documents. Tokens likewise come from
 * src/client/ui/tokens.css — this file defines none, and a new control style
 * is a change to ui.css, reviewed as such (UI_PLAN.md §2.1).
 *
 * The one exception is fenced at the bottom: `.notice*`, the callout the
 * library has no component for yet, which both this file's pages and ~25
 * files in src/client render. It moves into ui.css with a `Notice` component.
 *
 * `bun run lint:css` (scripts/check-css.ts) checks all of this.
