/* ===========================================================================
   FitForRiders — Design System v3 · "O instrumento de medição" (paleta D)
   Identidade: fita métrica de alfaiate + placas de número de corrida,
   em TINTA (monocromático POC/Lightweight) + LARANJA DE SEGURANÇA.
   - Títulos e números: Barlow Condensed (self-hosted em fonts/, 3 pesos)
   - Corpo: fonte do sistema (site estático e rápido — sem dependências)
   - O laranja é o SINAL e aparece SÓ em três sítios: o marcador da régua
     (--hivis), o botão de compra (--signal) e o foco de teclado (--focus).
     Todo o resto é tinta e cinzas quentes. Sem verde, sem tema escuro.
