// Docs-only stylesheet, built by the `css` script through the shared css
// pipeline (.build/build-css.ts, with --no-prefix) into tmp-assets/css/;
// copy-assets serves it as /css/docs.css. Tabler variables are written with
// their public `--tblr-` prefix here: the inlined DocSearch stylesheet below
// has variables its JS sets at runtime, so the build must not rename any.

// switches themes on `html[data-theme=dark]`, which Tabler never sets. Mapping
// every colour onto a Tabler token fixes both: the modal matches the docs, and
// it follows the color mode through the `light-dark()` tokens.
