/* /demos/fix-lab page chrome (PF-S445).
 *
 * 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), so this page follows the system preference and the theme toggle
 * without a palette of its own. The state colors are the one exception,
 * declared with the same three-way discipline websocket-lab.css uses.
