   cases-and-nav.css
   Additive stylesheet. Load AFTER css/style.css.

   Covers:
   1. Navbar: stronger glassmorphism (desktop), sticky (already true
      in style.css, intensified here)
   2. Mobile bottom nav: ONE unified active-tab badge treatment shared
      by Home / Services / Cases / Talk — no partial styling, no stray
      indicators
   3. Category system: 4 fixed categories, each with one locked color
      + one locked icon, used identically on cards and detail pages
   4. Cases index: flagship block + card grid, each card categorized,
      with an "optimization achieved" stat block and an image slot
   5. Case detail page components
   6. Responsive: real breakpoints at 1024 / 768 / 480, tested widths,
      not assumed

   Uses variables already defined in :root by style.css:
   --blue --teal --plum --blue-hi --teal-hi --plum-hi --bg --panel
   --panel2 --line --ink --dim --white --grad-h --grad-v --display
   --display-x --sans --maxw --pad
