/* ==========================================================================
   Carrossel - bloco reutilizavel (usa os tokens do style.css)
   --------------------------------------------------------------------------
   Dois componentes:
     .slideshow  - fotos em crossfade, uma por vez, cobre o fundo (hero)
     .carousel   - trilho com rolagem/snap, N por vez, setas, bolinhas e
                   autoplay (galerias). N vem de --per-view.
   O JS que anima esta em js/carrossel.js. Sem JS os dois ainda funcionam:
   o slideshow mostra a primeira foto e o carousel vira rolagem horizontal.
