   GameJam Føroya landing page. Vanilla, BEM, CSS custom
   properties for every design decision (Orlando Studio
   conventions). No @import, no framework.

   BRAND (v2 — balanced, not wall-to-wall teal):
     · teal  #039685  → the "frame": nav, hero, footer + accents
     · light-blue #90bae6 → soft surfaces, tints, hovers
     · white #f4f4f4  → the airy body background + card text
     · red   #ca4e3a  → the action/spark colour (buttons, badges)
   The body is light and airy so the teal reads as punctuation,
   not a flood. Typography is Alata (single weight); headings
   get presence from scale + uppercase + tracking, not boldness.
