/**

 *
 * SYNC: packages/dom/src/styles.css is byte-for-byte identical to this file
 * (@usefillo/dom builds its published CSS from its own copy via
 * scripts/build-css.mjs --src src/styles.css). Edit BOTH together.

 * A lint test (packages/react/test) fails the build on regressions. */
/* Cascade layers: these defaults live in the `components` layer so that, in
 * apps using Tailwind (or any utility CSS in the `utilities` layer), YOUR
 * classes always win over ours — className="bg-red-50" on an option just
 * works. Without Tailwind the layer has no competition and nothing changes. */
