/*
 * Perth BitDevs — shared slide-deck chrome.
 *
 * The header bar, slide pane, footer-nav, and the canonical card/hero/grid/
 * disclosure/links component vocabulary that every slide-deck page reuses.
 * Mirrors the rules in templates/slide-deck.html.tmpl. Per-page <style>
 * blocks load after this file, so topic pages can still extend or override
 * any rule with a per-topic bespoke component.
 *
 * Not loaded on landing/about/month-hub pages — those don't have the slide
 * chrome vocabulary. Auxiliary visual pages use a different chrome and
 * supply their own inline CSS.
 *
 * See agent_docs/slide-page-conventions.md for the contract this module
 * implements.
