   Palette: "Modern Navy" (PRODUCT.md brand commitment, 27 July 2026):
   #0A192F / #1E3A5F / #345B7D / #78909C / #CFD8DC, strong and modern.
   Navy is the primary; derived light neutrals (#ECEFF1 bg) and a darkened
   muted (#4C606D) keep every text pair at WCAG AA (verified, not eyeballed).
   Depth rules: elevation hierarchy, layered shadows, tinted surfaces,
   band overlap. No side-tab accent borders, no flat card stacks. */
