/* Sebelumnya file ini di-generate dari Tailwind v4 (@theme/@utility) yang butuh
   proses build Vite. Sekarang ditulis sebagai CSS biasa (custom properties +
   beberapa utility class) supaya jalan tanpa build step apa pun — Tailwind
   dipakai lewat CDN (lihat views/layout.ejs) hanya untuk utility spacing/flex/grid. */
