   PT LINKBIT INOVASI TEKNOLOGI - ISOLIR PAGE
   Dark + Light Theme, Glassmorphism

   TEMA
   Tema dipilih lewat atribut data-theme pada <html>:
     <html data-theme="dark">  atau  <html data-theme="light">
   Nilai disimpan di localStorage kunci 'linkbit_tema'. Bila pengunjung
   belum pernah memilih, prefers-color-scheme sistem yang dipakai.

   Hanya warna yang berubah. Tidak ada kaitan dengan API_BASE, API_KEY,
   WA_NOMOR, atau logika Cek Tagihan.

   Token dibagi dua lapis:
     1. Token mentah (--gray-*, --dark, --white) = palet, dibalik per tema.
     2. Token semantik (--surface, --text-*, --on-accent) = peran, dipakai
        aturan baru. Token mentah dipertahankan agar aturan lama tetap jalan.

   --on-accent SELALU putih di kedua tema: warna teks di atas tombol
   berlatar primary/danger/success yang tetap gelap, jadi tidak boleh ikut
   dibalik. Judul memakai --text-strong yang memang dibalik.
