/* ==========================================================================
   landing-starter — a galeria do catálogo

   Página de índice publicada na raiz do Pages; os demos vivem em /classic/
   e /aurora/, e os zips em /downloads/ (gerados por tools/build-site.mjs).
   Mesma família visual da Aurora (escuro, hairline, glow), sem toggle:
   o catálogo é uma página só, direta ao ponto.
