/* ════════════════════════════════════════════════════════════════════════
   Páginas legais públicas — /legal/privacidade.html e /legal/termos.html.

   Ficheiro próprio (sem <style> nem style="" nas páginas) para a CSP poder
   ficar com style-src 'self'. Cores da marca tiradas de src/styles/tokens.css:
   papel #F8F7F5, tinta #16181C, linha #E4E1DC, laranja #FF5A1F.

   Contraste (WCAG AA):
     texto  #16181C / #F8F7F5 = 16,6:1   ·  escuro #F8F7F5 / #16181C = 16,6:1
     suave  #4A4E52 / #F8F7F5 =  7,8:1   ·  escuro #9AA0A8 / #16181C =  6,7:1
     links  #B23A12 / #F8F7F5 =  5,6:1   ·  escuro #FF5A1F / #16181C =  5,7:1
   O laranja vivo #FF5A1F sobre papel dá só 2,9:1, por isso no tema claro fica
   em elementos decorativos (traços, marcadores) e nunca em texto.

   As páginas não correm JavaScript: o tema escuro vem só de
   prefers-color-scheme (o data-theme da app não chega aqui).
