/*
 * Minimal shared shadow-root reset, prepended once to the bundled
 * `ds.css` every component links to (see `scripts/build-ds-css.mjs` in
 * src). The design-system skill requires a single global reset
 * (`global.css`), but that is light-DOM only and cannot reach into a
 * shadow root. This is the shadow-DOM equivalent: box-sizing plus a
 * token-driven focus ring.
 *
 * Focus-ring color on inverse surfaces is not handled with `:host-context`
 * here: `ds-section[data-surface="inverse"]` re-points the
 * `--elvaio-color-focus` custom property for its whole subtree, and every
 * component (light or shadow DOM) that reads that token for its focus ring
 * inherits the override automatically, because custom properties inherit
 * through shadow boundaries.
