/* ==========================================================================
   Nav.ai — Design System v2 (Mintlify-inspired refinement)
   --------------------------------------------------------------------------
   Loaded AFTER all other stylesheets. Adopts the Do's/Don'ts and component
   patterns from DESIGN.md without changing the brand palette (deep navy
   #0b2e34 + lime accent #9be235 stay).

   Key shifts vs. v1:
   - Typography: General Sans for UI, Instrument Serif for H1-H2 display
   - Buttons: pill geometry (border-radius 9999px), keep 44px touch height
   - Sidebar active item: 3px navy left-border accent
   - New: alert containers (info / success / warning / error)
   - New: highlighted card (lime-tinted bg + navy border)
   - New: search input with icon (pill container)
   - Form focus: 3px navy halo ring (was outline-only)
   - Form helper / error text spec
   - Keyboard / code button (Geist Mono)
   - Pill badges with colored borders
   - Soft, navy-tinted hover shadows
   - Ghost button standardisation

   styles in theme.css / styles.css / dashboard*.css / workspace.css are
