/* ── features.css — page-specific layer for /features/ ──
   Loads after tokens.css + style.css. Scoped to .feat-* only. Everything
   else on the page — .section-head, .feature-card family, .tier-card,
   .steps-grid/.step-card, .hero-visual-frame + .hero-qa carousel,
   .t-line transcript bubbles, .mode-card, .cta-banner, .reveal — is the
   shared component from style.css and must not be redefined here (two
   past incidents: .cta-banner and .reveal were silently overridden by
   this file). Layout tweaks to a shared component go through a .feat-*
   parent selector, never the bare class. Tokens only — no literal colours,
   radii, or font sizes. See .claude/skills/marketing-design-system. */
