CYRIL CRESPO — PORTAIL
style.css — V5.0
----------------------------------------------------------------------
Base visual system only.

Responsive layout is split into:
  - responsive_paysage.css  : landscape / desktop / tablet landscape
  - responsive_portrait.css : portrait / mobile / tablet portrait

Photo slideshow is handled by:
  - portal.js

Design principles:
  - Three independent portal cards.
  - Images are always top-aligned.
  - No global card container around the three portals.
  - The 2560×1440 composition is the reference baseline.
