/* ═══ PAYWALL / ENTITLEMENT ══════════════════════════════════════════════
   The gate veil and the pricing card. Namespaced .vt-* and driven by the
   site's own custom properties, so light and dark are inherited.

   Two rules this stylesheet exists to enforce:
     · nothing that TEACHES is ever behind the veil — only metered extras
     · the veil is dismissible. A gate that cannot be closed is a trap, and a
       trap on the reading pages would cost the search traffic outright.

/* ── headings inside the plans page ──────────────────────────────────
   shapes-skin.css paints a white→pale-blue gradient onto EVERY h1/h2/h3 in dark
   mode: `body.dark h1 { background-image: ... !important }`. It sets only the
   image, so whether the words are visible depends entirely on whether some
   LATER rule also sets -webkit-background-clip:text. The home page gets that
   from a hero-specific rule, so a bare h1 there keeps an opaque fill and the
   gradient renders as a pale slab with invisible text — which is what the
   pricing page looked like.

   So both halves are set explicitly here. The clip is what makes the gradient
   visible as text; the fill colour is the fallback for a theme that removes the
   clip again. */

/* == Buttons on this page ==
   pricing.html has no inline stylesheet, so `.qo-btn` -- which every other
   page defines in its own <style> -- was never defined here. That left the
   plan CTAs and the study-pack download as bare text: measured 271x18px,
   far below the 40px tap floor.

   soft-glass.css already skins `.qo-btn` globally, with !important on
   background/colour/border, so this block must NOT try to restyle it -- an
   earlier attempt at accent-gold buttons was silently overridden and came
   out as a grey pill. This supplies LAYOUT only and lets the design system
   own the appearance. Scoped to IDs that exist only on this page, so
   nothing leaks onto exam / cn-cert / ib-sehs-learn / home. */
