/*
 * LabsNinja marketing shell — shared MNav + MFooter (redesign F1).
 *
 * Faithful port of the authoritative design's MNav / MFooter
 * (design_handoff_scim_platform/design_reference/marketing.jsx): sticky
 * blur nav with centered links + active indigo underline, and a multi-column
 * footer with a mono/uppercase column headers + bottom bar. Adapted to the real
 * site — reads the canonical --ln-* tokens (tokens.css) and keeps the site's
 * 1200px centered container.
 *
 * TRUTHFUL GATES (deliberate divergence from the artboard — see
 * ai-review-loop/UI_REDESIGN_GAP_MATRIX_2026-07-28.md):
 *   - CTA is "Start free", NOT "Start free trial" (perpetual-free Developer tier).
 *   - NO "SOC 2 · ISO 27001 · HIPAA · GDPR" compliance line (we hold none).
 *   - NO "All systems normal" live-status pill (we publish no live status).
 *
 * Namespaced .ln-mnav* / .ln-mfoot* so it never collides with the per-page
 * inline marketing styles during the incremental page migration. No Inter.
