/* /demos/crdt-lab page chrome (PF-S421).
 *
 * Loaded only by this page, through Tags.PageCSS; the ?v= in PageCSSHref is the
 * whole cache-busting story. Colors come from the shared sheet's custom
 * properties (--ink, --ink-muted, --hairline, --surface, --surface-alt,
 * --accent), which css.css redeclares under both the system dark preference and
 * the explicit theme toggle — so this page follows both without a palette of
 * its own. The two status colors are the one exception, declared here with the
 * same three-way discipline.
