/* AptiStockX static website — dark-primary design system.
   Aligned with CLAUDE.MD §2:
     - Dark theme primary, light theme alternative for long-form docs
     - Single accent #26A69A (matches in-app chart "up" color)
     - Gold reserved for AptiStock lineage / heritage only — never a CTA
     - Semantic green/red exclusively for up/down
   Portable: pages open directly from the filesystem. */
