/*
 * theme-extras.css
 *
 * The hengjitai theme ships a pre-purged Tailwind bundle (combined.min.css)
 * generated from the ORIGINAL hengjitai-pipeline-site templates. Any utility
 * class that the original site never used is missing from that bundle.
 *
 * This file supplements the bundle with extra responsive / layout / sizing
 * utilities that the site-forge-version partials (notably the responsive
 * header, mobile drawer, and module hooks) depend on. It is intentionally
 * narrow: only classes that DO appear in our templates but DO NOT exist in
 * combined.min.css.
 *
 * If you add new Tailwind utilities to a partial and they don't render,
 * verify with:
 *     grep -F '.your-class' themes/<theme>/assets/css/combined.min.css
 * and add the missing rule here.
 */

/* ---------- sizing ---------- */

   different size!) but NOT bare .w-3 / .h-3. Without these, any svg with
   `class="w-3 h-3"` renders at default svg size (~300x150), which is what
   made the lang-switcher / nav dropdown chevrons huge. */
