/* ═══════════════════════════════════════════════════════════
   VEXTALEARN — Premium landing page stylesheet
   (Premium Frontend Phase 1)

   Scoped entirely to body.premium-landing, exactly like home.css
   is scoped to body.homepage. Every color/spacing/radius/shadow
   value below is one of the existing tokens from main.css
   (--primary, --accent, --gradient-brand, --surface, --border,
   --radius*, --shadow*, --font-display/--font-body) — no new
   palette, no new type system. New class names use a `.vxprem-`
   prefix so nothing here can collide with existing selectors;
   where an existing shared component already does the job
   (.vxt-btn-primary, .vxt-btn-outline, .pricing-card family,
   .vxt-accordion, .vxt-empty, .section-label) this file reuses
   it directly instead of redefining it.

   Dark mode: no overrides needed here — every value is a token,
   and html[data-theme="dark"] already redefines those tokens
   globally in main.css, exactly like home.css relies on.
