/* Wacana — Feed & PostCard (PRD Bagian 17, 22, 54) */
/* Kartu adalah unit visual utama app — latar warnanya berotasi lewat palet
   brand (putih/abu/hijau/ungu) sebagai identitas UI utama, bukan cuma aksen
   kecil di tombol. Karena semua elemen di dalam kartu memakai var(--color-text)
   dkk, cukup override custom property di level kartu supaya kontras teks
   otomatis menyesuaikan warna latar — tidak perlu sentuh file lain. */
