   Palet RAMAH LANSIA / MATA RABUN:
   - Kontras tinggi (teks >= 7:1, standar WCAG AAA)
   - Warna hangat (krem, amber, cokelat) - lebih nyaman karena
     lensa mata lansia menguning dan kurang peka warna biru
   - Hindari putih murni di atas hitam murni (silau/bayangan)
   - Ikon & huruf lebih besar, garis tepi tegas, fokus jelas
   Ubah warna cukup di blok VARIABEL di bawah.
