/*
  buatbelajar — teacher dashboard prototype
  Direction: "Map Snelhecter" (see website/DESIGN.md), calmed down for daily use
  by teachers of any age.
  - Folder blue = navigation ground. Paper = every content surface.
  - Tab Yellow = the ONE next action on a screen. Never decoration.
  - Sharp corners everywhere. Atkinson Hyperlegible throughout: 700 for headings (28–36px titles, 22–26px sections), 400 body at 18px+ / 1.55.
  - Base text 18px, 48px tap targets, labels on every icon.
  Signature: the four-step folder-tab path on Beranda.
