/* ============================================================================
   DESIGN_GUIDE.md v3 — official brand palette + typography.
   Corrects Step 1's placeholder palette. Loaded AFTER style.css so values win.

   Brand: Vibrant Blue #1D70B8, Deep Teal #008080, Dark Navy #1A237E.
   Accent shades verified with a WCAG AA contrast audit (see outputs/59):
     - dark --accent #3D8FD6 (lightened Vibrant Blue): link text 5.15-5.60:1
     - --accent-strong #1D70B8 (true brand): white button text 5.17:1
     - --accent-secondary #1FA3A3 (dark): text/outline/highlight ONLY — white
       text on a #1FA3A3 fill is 3.08:1 (fails), so never fill+white with it.

/* ============================================================================
   v3 STEP 4 — Sweep: align legacy content-page cards with the new component
   system (feat/66). About / Privacy / Terms / blog / contact / 404 are styled in
   style.css via the remapped legacy tokens, so they already pick up the palette
   and fonts. Two things fought the new look: they used --secondary-color (the
   muted body-text grey) for card BORDERS instead of --border-color, and justified
   body text. Re-point borders to --border-color and left-align. Additive overrides
   (theme.css loads after style.css). Admin panel is a separate flag — see output.
