/* =====================================================================
   CSS WARISAN sebelum proyek memakai Tailwind.
   Ditulis tangan, TIDAK ikut proses build.

   Dari 10 kelas di sini, 9 sudah tidak dipakai halaman mana pun.
   Yang masih terpakai hanya:
     .grad-vibrant-brand   -> index.html versi origin/main

   (.text-brand-primary ikut menganggur setelah tutorial.html dihapus.)

   Berkas ini sebaiknya dilebur ke src/input.css lalu dihapus, TAPI baru
   aman dikerjakan setelah branch ini digabung dengan origin/main —
   halaman di sana masih memuatnya.
