/* base.css - reset, typography and the UI kit components built by js/ui.js:
   buttons, icon buttons, inputs, selects, number fields, segmented controls, switches,
   sliders, tabs, form rows, menus, popovers, modals, toasts, tooltips, colour swatches,
   the colour and font pickers and the busy overlay.
   Colours, fonts, radii and shadows come only from tokens.css. Safety orange here: primary
   buttons are solid --accent with --on-accent text; switches (on), slider fills, progress
   bars and the default toast edge use --accent-line; the highlighter swipe (--swipe) marks
   pressed buttons and selected tabs. Focus rings stay --ink. */
