/* ═══════════════════════════════════════════════════════════════════════
   Respira: meditação. Visual calmo, muito ar, sem fontes de terceiros (pilha do sistema, que também abre sem internet).
   Tema: claro por padrão, escuro quando o sistema pede (prefers-color-scheme) e as duas escolhas manuais (html[data-theme]).
   Os tokens de cada tema ficam nos três blocos marcados com `@theme`: test/respira-page.test.js confere o contraste de cada par e que
   os três declaram as mesmas variáveis. A tela da meditação é sempre escura (menos luz no rosto de quem fecha os olhos).
   Movimento: o script do <head> põe data-motion="reduced" no <html> quando a pessoa pede menos movimento.
