/*
 * Site chrome — canonical styles for the main ecosystem nav bar,
 * the product-level sub-nav, and the footer. Linked by every
 * marketing page via <link rel="stylesheet" href="/css/site-chrome.css">.
 *
 * Goal: a single source of truth for header/footer styling so the
 * 16 marketing pages can't drift visually. Per-page <style> blocks
 * may define additional component CSS but should not redefine these
 * selectors. The standardize-chrome.js verifier enforces structural
 * coherence; visual coherence relies on this file being authoritative.
 *
 * Two-tier header layout:
 *   .hq-nav        — fixed, 52 px, ecosystem-level links
 *   .hq-sub-nav    — inline, ALETHEIA product-level links + CTA
 *
 * Footer is a 3-column grid that collapses to a single column on
 * narrow viewports.
