/* ============================================================
   PONTE — design system v2
   Same language as the Roots Football Academy site: modernist,
   flat surfaces, ruled lines, no rounded corners, flush-left,
   numbered sections, ONE accent colour.
   Own palette (navy + copper) so PONTE reads as a separate business.
   Fonts are self-hosted: Google Fonts is blocked in mainland China.
   Chinese falls back to system serifs (Songti / Source Han / SimSun).
