/* ============================================================
   Tarjetas de caso simples y listas numeradas
   La clienta reporto (14-set-2026) mini casos y listas que salian
   como texto corrido, sin tarjeta ni separacion visual. Dos causas:

   1) Hay tarjetas cuyo titulo cuelga directo de .case-card
      (<div class="cc-label">) y no de un .cc-block. La unica regla
      para esa clase era .cc-block .cc-label, asi que el titulo
      quedaba como parrafo y las citas sin margen ni color.
   2) .info-list se veia como una lista con lineas finas. El resto
      del curso usa tarjetas, asi que cada item pasa a ser una.
