/*
 * Site search (assets/search.js): a floating button stacked above the page
 * helper, and a modal. Same tokens as theme.css, with fallbacks.
 *
 * Stack, bottom-right: theme toggle (14px), helper launcher (68px), search
 * (122px). The search button sits below the helper in z-order, so an open
 * helper panel covers it rather than the other way round.
