/* ============================================================
   FLUVIAL ENGINEERING — site stylesheet
   One system, two contexts, both theme-aware:
     • shell     (default)  → landing and full-bleed screens
     • .reading             → prose pages: services, who is, contact
   Theme pair: dark (default) / light. Every colour is a token;
   a rebrand is a change of variables, not a rewrite.
   Type: Carlito, the metric-compatible open equivalent of the
   firm's document standard, Calibri.
