/* Calendar's own styles.
 *
 * The rule (CLAUDE.md rule 5, packages/design/README.md): this file may CONSUME
 * semantic tokens and nothing else. No raw values, no redefining a `.ds-*`
 * component, no reaching for a primitive ramp. The app's accent is repointed in
 * `packages/design/css/app-themes.css` under `[data-app="calendar"]`, not here,
 * and a diary's colour comes from the `--ds-cat-*` set in tokens.css rather than
 * from a hex anybody picked — which is why the database stores the NAME.
 *
 * Everything is prefixed `cal-`. A grid is the one thing the design system has
 * no component for, and it is the whole of this file.
