/*
 * Hearthstead component library (Roadmap/49 D4).
 *
 * Every class is prefixed hs- so it never collides with the legacy
 * components.css / style.css classes, which stay for the old page bodies
 * until D5-D7 rebuild them. Colours, type, spacing, radii, elevation and
 * motion come from css/tokens.css only, so everything follows the theme.
 * The live catalogue is /styleguide.html. Behaviour (dialogs, toasts,
 * menus, tooltips, meters) lives in /js/ui.js; the data grid in
 * /js/hs-grid.js.
 *
 * Touch: on coarse pointers every control reaches 44 px.
