   IMAGE SAFETY — Reglas universales para que
   NINGUNA imagen rompa el layout o se distorsione,
   sin importar el tamaño/proporción de archivo subido.

   Estrategia:
   1. Todas las <img> sin object-fit explícito → contain (NO se estiran)
   2. Todas las <img> dentro de aspect-ratio containers → cover
   3. Backgrounds con url() → cover + center + no-repeat
   4. Logos: contain (preservan proporción, no rellenan)
   5. Fotos en cards/grids: cover (recortan pero no deforman)
