   tailwind.css — CSS statis mandiri (pengganti https://cdn.tailwindcss.com)
   =========================================================================
   Hanya memuat:
     1. Preflight (reset dasar) dari Tailwind CSS v3.4.17, dan
     2. Kelas utility yang benar-benar dipakai index.html + app.js.

   Nama kelas identik dengan Tailwind, jadi markup tidak berubah sama sekali.

   PERHATIAN: bila menambah kelas Tailwind baru di index.html/app.js,
   tambahkan aturannya juga di sini (atau kembalikan Play CDN untuk dev).
