   Palet "merah & putih, sedang jatuh cinta":
   - merah anggur dalam (red-950 #450a0a, red-900 #7f1d1d) untuk section gelap
   - putih & blush lembut (white, rose-50 #fff1f2) untuk section terang
   - aksen rose (rose-300/400/500/600) untuk label, border, tombol
   - #2b0709 (arbitrary, lebih gelap dari red-950) untuk footer/preloader/overlay
   Semua dipakai lewat class Tailwind bawaan (red-*, rose-*, white) atau
   nilai arbitrary bg-[#...] — tidak perlu ubah tailwind.config.js.
