/* fotos-viagem: as transições da skill transitions-dev que não moram em app.css.
   As que já estavam em app.css (02, 06, 07, 08, 10, 12, 14, 16, 21, 22, 27, 33)
   continuam lá. Aqui ficam as outras 22, coladas como a skill entrega, com três
   ajustes, todos pela paleta fechada ou por conflito de nome:
   - cor literal da receita vira token da paleta (tokens.css) ou color-mix com token;
   - máscara (só o alfa importa) usa var(--tinta) no lugar de preto;
   - a 20 (plus para menu) usa o mesmo nome .t-morph da 33 (text morph, já no
     botão Salvar). Os seletores da 20 ficam restritos a .t-morph[data-open], que é
     o HTML documentado da 20; o .t-morph da 33 não tem data-open.
   Carregado entre tokens.css e app.css: o layout de app.css vence onde se cruzam.
