/* palette.css — R291 (W8-palette / U15) command palette + shortcuts modal styling.
 *
 * Scoped to the canonical openModal({id:'palette'|'shortcuts'}) backdrop
 * built by kit/_palette.js + kit/_shortcuts-modal.js. The .modal-backdrop
 * + .modal class chain comes from kit/modals.js; this file just styles
 * the inner palette/shortcuts content. All colors, radii, and durations
 * pull from frontend/web/src/colors_and_type.css design tokens.
 *
 * Why a separate file?
 *  - kit/index.html already has ~2680 lines of inline <style>, audit
 *    P2-U15 flagged this duplication. New surfaces live in CSS files.
 *  - palette + shortcuts share kbd/row styling — collocate so changes
 *    stay in sync.
