/* Shared "Agent TechPort" top nav bar.
 * Single source of truth — linked by landing (/), /using-techport-mcp/,
 * and all KB pages. Do not duplicate these rules elsewhere.
 *
 * Two rendering contexts:
 *   1. Static HTML pages wrap the bar in .agent-topbar > .agent-topbar-inner.
 *   2. MkDocs Material KB pages render the bar inside Material's
 *      .md-banner > .md-banner__inner announce block; the rules below
 *      override Material's defaults so the look matches.
