/* guarder.io — the public site.
 *
 * THE IDEA, so later edits keep it: a network is quiet until it is not.
 * The page is built on that rhythm — a steady, regular measure interrupted
 * at exact points by real events. That is why the live strip runs the full
 * width and everything else is calm around it, and why colour is spent
 * ONLY on data: green/amber/red mean a severity, never decoration. If you
 * are about to colour something because it looked plain, don't.
 *
 * Type does the work instead. Manrope is variable (200-800) and the range
 * is used deliberately: display sizes sit at 300 so they read as calm
 * rather than shouted, small labels at 600-700. IBM Plex Mono is reserved
 * for measured values — counts, timestamps, IPs, axis ticks — so monospace
 * always means "this is a reading".
 *
 * No inline styles anywhere, and no external anything: hub/tests/
 * test_site_csp.py enforces both (CSP is default-src 'self'), which is
 * also why the charts in app.js are hand-rolled SVG rather than a library.
