/* ==========================================================================
   SHARK Futures, shared landing-page stylesheet
   Tokens are verbatim from ~/.claude/design-tokens/shark.design.md (Color
   System v1.0). Green-400 #0CF25D is the primary accent at ALL times; cyan is
   strictly secondary and is not used on these pages at all.

   Deliberate deviation from the live Kit page: the Kit build declares
   `Inter, Helvetica, Arial` and never loads Inter, so it actually renders in
   Arial Black. We load Inter Tight, which is the real brand face. Same
   layout, same copy, same colours, correct typography.
