/* ============================================================
   UNLEVERED — Shared marketing primitives
   ------------------------------------------------------------
   Canonical home for cross-page marketing primitives:
   container, marketing nav, footer, deliverables band.

   Linked by every marketing page (index, about, contact,
   estimate, faq, for-tax-professionals, how-it-works, pricing,
   sample-study, security, str-calculator).

   Page-specific layout (hero, cutaway mount, ptype, platform,
   faq sections) lives in site.css. App-shell primitives
   (.nav, etc.) live in components.css.

   Locked 2026-05-22 per design audit (see 04_BRANDING.md §13.x
   CSS ownership).
