/* AI Accuracy Lab: primary CTA gradient (23 Oct 2026, Shane: "all CTAs get the same gradient look as Get a quote").
   One class, .btn-grad, added to the primary CTA <a>/<button> on top of .btn (+ .btn-primary). .nav-cta (the "Subscribe" header
   button on the older css/styles.css pages) gets the same look. Linked on every page by /workspace/handoff-build/headdot.py,
   after site.css / styles.css / shell.css, so it wins over their yellow .btn-primary / .ns .btn-primary !important overrides.
   Look = the 15 Oct "Get a quote" pricing button, unchanged:
   - fill linear-gradient(95deg, #FFD60A 0%, #FFD60A 55%, #FF8A00 80%, #F2501E 100%), ink #1D1D1F text
     (contrast 11.9:1 on #FFD60A, 7.1:1 on #FF8A00, 4.76:1 on #F2501E; AA 4.5:1 everywhere), pill radius 999px, no drop shadow
   - hover: 1px ink edge (border + inset ring) and underline; active: 2px inset ink ring
   - keyboard focus: 3px ink outline, 3px offset; forced colours: 2px ButtonText border
   Not for utility buttons (form submits in dialogs, game controls, exports, toggles, nav links).
   23 Oct 2026 (e), Shane: ONE gradient CTA per screen/section, for the single main action; every other button in that
   section uses the outline style (.btn-secondary on site.css pages, .btn-outline on styles.css pages). The header
   "Get access" / "Subscribe" button may stay gradient as the nav's single CTA. .nav-cta is now opt-in (.nav-cta.btn-grad,
   public pages only) so signed-in screens keep their calm, non-gradient header. */
