/* ============================================================
   YAOUNDÉ ENSEMBLE — design tokens (v2: light, real flag colors)
   Cameroon's flag is three bold, unmixed colors — green, red, gold —
   on nothing but plain ground. That's the brief here too: a bright,
   sunlit cream background instead of a dark panel, and the three flag
   colors used as-is (not muted or desaturated) for CTAs, the signature
   ribbon, and accents. The "taxi board" motif stays — it's still the
   most Yaoundé thing about this app — just rebuilt for daylight.
