/*
 * kit.css · the Studio Fabi tools kit (Capsule Dock)
 *
 * Every shared component, one class name each, built only from tokens.css.
 * The subject is the page; one capsule (the dock) at the bottom holds the
 * settings; a chip opens one sheet on the right; the navy split primary ends
 * the dock. kit.js runs the behaviour. See kit/README.md for the API.
 *
 *  1 Base and utilities           12 Swatches, hex, colour popover
 *  2 Ground and header            13 Switch rows, sliders, stepper
 *  3 Stage, layouts, tray        14 Fields, upload tile, file row
 *  4 Hero field and readout       15 Buttons and toggles
 *  5 Status pill and notices      16 Popovers, menus, options pop
 *  6 Dock, chips, bubbles         17 Tooltip, toast, drop overlay
 *  7 Split primary                18 Dialogs and the phone notice
 *  8 Sheet and panels             19 Item lists and rows
 *  9 Sections, folds, (i)         20 Transport, tool palettes
 * 10 Segmented control            21 Progress, empty state, page mode
 * 11 Tiles, presets, preset chips 22 Responsive, touch, reduced motion
 *
 * Rules: element defaults use :where() so a tool's CSS always wins; no
 * colour or radius literals here except the custom swatch's hue wheel (and
 * #000 inside masks, where only the alpha counts); a tool adds CSS only for
 * its own subject, from tokens.
 *
 * Class names a tool's own markup may reuse without picking up kit styles:
 * .item (only .items > .item is styled), .lock (only svg.i.lock), .badge
 * (only on .tile and .preset-art), .sw (only button.sw), .pop (only div.pop),
 * .info (only button.info), .play (only .icon-btn.play), .time (only inside
 * .transport). Every other class here is the kit's: see PORTING.md, "Reserved
 * class names".
