/* =========================================================================
   HKB-inspired readability upgrades (2026-08-18)
   - Section titles become left-aligned "title bars" with a gold accent, so
     readers always know where a new topic starts (scannable, low cognitive load).
   - Content h2/h3 get visible anchors (gold marker) for long-page scanning.
   - Color restraint: gold stays the single action color; secondary buttons use
     a navy outline; inline links use a calmer blue (less neon competition).
   - Cards get a subtle gold top accent ("labeled header" feel).
