/*
 * Shared UI core for the storefront and the admin: design tokens (light +
 * dark), base elements, the standard components (buttons, form fields,
 * cards, badges, alerts, tables, tabs, key/value lists, stat cards, empty
 * states, pagination) and a small set of utilities.
 *
 * shop-core.css and admin-core.css add their own chrome on top in the same
 * layers. Page <style> blocks are unlayered, so they always win over these
 * files without !important. Colours in page styles must come from the tokens
 * below so dark mode works.
 *
 * Contents
 *   1. Tokens ............ colours, radius, control height, fonts (light + dark)
 *   2. Base .............. body, headings, links, form controls, tables
 *   3. Components
 *      3.1 Buttons ........ .btn  .btn-light .btn-outline .btn-ghost .btn-danger .btn-ok

 *      3.2 Forms .......... .field .hint .error .form-grid (.wide spans the row) .form-actions .check .input-group
 *      3.3 Cards .......... .card .card-head .card-flush .card-foot, details.card
 *      3.4 Page head ...... .page-head .page-actions
 *      3.5 Badges ......... .badge  -green -yellow -red -blue -primary
 *      3.6 Alerts ......... .alert  -success -error -warn -info
 *      3.7 Tables ......... .table-wrap, td.num, .table-cards (rows as cards on phones)
 *      3.8 Key/value ...... .kv (dl/dt/dd), .kv-sm, .copy-value + [data-copy] buttons
 *      3.9 Tabs ........... .tabs (.on), .seg (.on)
 *      3.10 Stats ......... .stats (.stats-2 .stats-3) .stat

 *      3.12 Pagination .... .pager .pagination
 *      3.13 Secret value .. .secret
 *      3.14 Modal ......... .modal-backdrop(.open) .modal, .ui-confirm (UiConfirm dialog)
 *      3.15 Progress ...... .progress > span (width = done %)
 *      3.16 Timeline ...... .timeline (order progress, complaint steps)
 *      3.17 Order chat .... .order-chat, .oc-msg
