/*
 * Pattern: wrapper posizionato + immagine assoluta che riempie il container.
 * Usare un <div class="media"> lascia <figure> libero per la semantica HTML:
 *
 *   Semplice:
 *   <div class="media" style="aspect-ratio: 16/9">
 *       <img class="img-cover" src="..." alt="..." loading="lazy">
 *   </div>
 *
 *   Con caption (semantica corretta):
 *   <figure>
 *       <div class="media" style="aspect-ratio: 16/9">
 *           <img class="img-cover" src="..." alt="..." loading="lazy">
 *       </div>
 *       <figcaption>Didascalia</figcaption>
 *   </figure>
 *
 * .media       — wrapper (position: relative, display: block)
 * .media-bg    — wrapper decorativo: no pointer-events, no select.
 *                Supporta ::after per overlay (solo su <div>, non su <img>)
 * .img-cover   — riempie il wrapper, object-fit: cover   (foto, hero, card)
 * .img-contain — riempie il wrapper, object-fit: contain (loghi, illustrazioni)
 * .img-scale   — riempie il wrapper, object-fit: scale-down (icone, asset misti)
 *
 * NB: Bootstrap ha .object-fit-cover ecc. ma senza il posizionamento assoluto —
 * queste classi coprono il pattern "fill container" completo.
