  PANDU - SIGNUP CSS
  Lokasi file: ./css/signup.css

  UPDATE FINAL SELARAS LOGIN:
  - CSS disesuaikan dengan struktur signup.html terbaru.
  - Badge PANDU Mobile Apps kiri atas dihapus dari tampilan.
  - Card kiri memakai .signup-visual-card.
  - Card kanan memakai .signup-card-shell.
  - Layout, font, warna, shadow, radius, dan visual dibuat selaras login.css.
  - ID penting signup.js tetap aman karena tidak diubah.
