/* =========================================================================
   Growth Club — Components (canonical UI Kit + retrocompat with v1)

   AD-008 light-first classes retained for backwards compat (other pages
   still use .btn-primary, .card, .cards-grid, .split-two, etc.).

   Canonical UI Kit classes (from brand-adapt/.../ui_kits/website/) added
   alongside: .wrap, .btn.primary/.btn.ghost, .eyebrow, .eye-label,
   .kicker, .sec-head, .stats-row, .problem-grid, .layers, .timeline,
   .manifesto-big, .quote-section, .cta-final, .cta-inline, .hero-sub,
   .crumb, .toc, .prose, .pull, .author-strip, .meta-row, .inline-arrow,
   h1.mega, h1.page-title.

   Light-first: html sem data-theme = tokens light (Pub Cream + Growth Black).
   Dark via data-theme="dark" em sections especificas (hero da home + cta-final).
