   SITE EXPRESS — v3
   Hybrid light/dark page, reusing v1 styles for hero/nav/static
   sections and adding LIGHT-themed versions of v2 mechanics:
     - .v3-hpin    (horizontal pin "Como funciona")
     - .v3-stack   (sticky stack "Por que")
     - .v3-show    (scroll-driven showcase)
   Plus a small theme-switcher (v1/v2/v3) bar in top-left.
