   Avarith Learn — landing.css
   Styling section landing: nav (di base) → hero → hook → how → wow-blurt →
   wow-lembah → why → waitlist → footer (di base). Plus sheet return-from-demo.

   BG selang-seling (per build-spec):
     hero #F3F6E7 → hook #FBFCF4 → how #F3F6E7 → wow-blurt #FBFCF4
     → wow-lembah #EDF1D6 → why #F3F6E7 → waitlist #3F513B (satu-satunya gelap)
   Restraint: 1 primary CTA / section, warna flat, 1 shadow lembut, no glow.
