   Ambiência: misturador de sons de ambiente (views/apps/ambiencia.eta)
   Só tema escuro (a página é uma noite com fundo animado). Os pares de cor que importam (texto, botão, rótulos de campo, foco) ficam no bloco
   `@theme`: test/ambiencia-page.test.js mede o contraste de cada par. A cor do projeto vem de --accent e --accent-2 (catálogo, no <html>).
   O movimento comum (pop, confete) vem de juice.css; juice.js põe data-motion="reduced" no <html>. Sem fontes de terceiros: o app abre sem internet.
