/* ==========================================================
   AI-CRIMS UNIFIED FEATURES SECTION
   Scoped strictly to .ai-crims-feature-grid / .ai-crims-feature-card /
   .ai-crims-feature-icon / .ai-crims-feature-kicker inside #features.
   Does not redefine .features, .feature-card, .features-grid,
   .core-feature-card, or any other existing selector.

   Palette reuses the --ai-* custom properties already declared on
   .ai-crims-features-section in final-polish.css (the same light,
   glass-card treatment this section was originally designed with),
   so the new cards match the section's existing look instead of
   introducing a second, flatter style.
