 * 1.  [STATIC-IMG]   Card com imagem — compacto e editorial
 * 2.  [EDITORIAL]    Card editorial estilo repositório/blog

 * 7.  [MEDIA-PANEL]  Painel visual de mídia / biblioteca
 *
 * LEGENDA DE TAGS (nos comentários dos componentes):
 *   [STATIC-IMG]  → recebe imagem estática (jpg, png, webp)
 *   [THUMB-VIDEO] → recebe thumbnail de vídeo (poster frame)
 *   [BG-IMAGE]    → recebe imagem como background-image CSS
 *   [BG-VIDEO]    → recebe <video> como fundo de seção
 *
 * REGRAS GLOBAIS DE MÍDIA:
 *   - Nunca width: 100vw em nenhum elemento
 *   - Imagens e vídeos: object-fit: cover com aspect-ratio fixo
 *   - Overlays: sempre via ::after, nunca elemento extra
 *   - Fallback mobile: aspect-ratio menor, sem autoplay
