   Design system + component styles.

   Palette: deep forest green primary, warm off-white background, soft
   natural greys. No dark theme, no loud accent colours, per spec.
   Typography: system font stack only (no external font requests) — keeps
   the page fully self-contained and fast on first load, and looks native
   and premium on iOS/Android/desktop alike.
