+## Bootstrap re-tematizado (2026-10-13)
+- `assets/css/bs-brand.css` (carregado depois do Bootstrap em `includes/header.php` e `includes/auth_header.php`) sobrescreve as cores do Bootstrap só com variáveis `--bs-*` e as variáveis de componente (`.btn-*`, `.form-check-input`, `.page-link`…), claro e escuro. A cor de marca é `--fitme-accent` (fallback `#C2D500`); todos os tons derivam dela com `color-mix()`; `--brand-on` é o texto sobre a cor. Secondary/success/danger/warning/info têm valores próprios. Verificação: `platform.php?tool=branding` (Montra da marca) não deve mostrar nenhum azul por omissão. O site público ainda não carrega este ficheiro.
