/* ==========================================================================
   Launch Labs — Hero
   Plus Jakarta Sans (headline) + Hanken Grotesk (nav/body/UI)
   Black is the default state; red and white are switchable variants.
   Structure: reset -> theme tokens -> nav -> hero atmosphere -> content ->
              headline -> support/cta -> focal visual -> scroll cue -> motion

   Two easing tiers (per emil-design-eng): --ease is the slower, expressive
   curve reserved for the one-time page-load reveal and ambient motion;
   --ease-ui is a snappier curve for anything the user directly triggers
   (hover, press, theme switch) and stays under ~250ms.
