/* Lakeville.ai — shared components (extracted 2026-05-17 by 014A).
 *
 * Source of canonical rule text: about.html
 * Codex consult: 20260517T042339Z-lakeville-ai-014a (GO with refinements).
 *
 * Order matters: tokens.css must load FIRST in the page so that
 * `var(--primary)` etc. resolves before these component rules.
 * Page-specific styles still live in the page's inline <style>.
 *
 * Components in this file:
 *   1. Nav topbar (incl. brand medallion, hover-glow, wordmark,
 *      .lk-medallion-clearance, dropdown panel)
 *   2. Mobile drawer (lk-menu — overlay + scroll panel + primary cards)
 *   3. Keyframes referenced by components
 *
 * NOT in this file (deferred to a future round):
 *   - Footer .trust / .trust-col / .trust-grid (3-way divergence
 *     across pages; needs visual convergence first)
