  /* ────────────────────────────────────────────────────────────────
     CONTRAST RECEIPTS - WCAG 2.2 SC 1.4.3 AA + SC 1.4.6 AAA
     ────────────────────────────────────────────────────────────────
     axe-core and most automated scanners CANNOT measure contrast on
     text painted with `background-clip: text` (the text has no single
     "color" value - every character spans a gradient). This is a
     known scanner blind spot, not a defect in this rule.

     The math below is computed against the worst-case combinations:
     each gradient stop measured against each possible background
     colour the hero section uses (white #ffffff at the top of the
     hero, slate-100 #f1f5f9 at the bottom via the linear-gradient
     fade in .hero). The radial-gradient overlays in .hero use 5–7 %
     opacity tints and shift effective background by less than ±0.5
     ratio points, so the table below is the binding worst case.

       Gradient stop                       | on #ffffff | on #f1f5f9
       ────────────────────────────────────|────────────|───────────
       0 %  --color-primary-dark  #082f49  |   13.88:1  |   12.67:1
       55 % --color-primary       #0c4a6e  |    9.46:1  |    8.63:1
       100% --color-primary-light #075280  |    8.31:1  |    7.58:1

     Every stop passes WCAG 2.2 SC 1.4.3 AA (≥4.5:1) and
     SC 1.4.6 AAA (≥7:1) on both background variants. The lightest
     stop on the lightest background (7.58:1) is the floor.

     If the gradient endpoints ever change, recompute the worst-case
     stop against #f1f5f9 and confirm it stays ≥7:1 before merging.
