/* ═══════════════════════════════════════════════════════════════════
   Customer panel UI kit (panel-ui.css)

   One set of parts for every in-panel page: page layout, summary tiles,
   card header, table, notice, status chip, buttons, form fields, empty
   state. Built on the --ep-* tokens from input.css, so dark and light
   follow automatically.

   Plain CSS, loaded after output.css by css_loader.php on the customer
   panel only (the admin has its own admin.css; the three surfaces keep
   separate designs). It is NOT compiled by Tailwind on purpose: the
   Tailwind config does not scan every folder that uses output.css, so a
   rebuild would silently drop live classes. Nothing here depends on a
   Tailwind utility existing.

   card keeps its contrast. */
