/*
 * adspot-ui.css  -  the shared look of adspot (design system v3).
 *
 * One file, three jobs:
 *   1. tokens      colours, radius, shadow, spacing and type (the :root block). Change one here, the whole product follows.
 *   2. the kit     .ui-* building blocks every page is made from (listed in the index below).
 *   3. shared UI   the message_alert dialog and the toasts, which any page can open.
 *
 * The top bar styles itself (a <style> block at the top of html/toolbar.html); the old legacy classes (.green_buttons, .campaign_card ...) live in main.css.
 * Link this file in the <head> of every page, after main.css:
 *     <link rel="stylesheet" href="/css/adspot-ui.css?v=20261101a">
 *
 * Index (search for the section name):
 *   LAYOUT      .ui-shell .ui-container .ui-page .ui-pagehead .ui-crumbs .ui-section .ui-grid .ui-cards .ui-stack .ui-row
 *   NAVIGATION  .ui-tabs .ui-tab  .ui-filterbar .ui-search .ui-chips .ui-chip  .ui-steps
 *   SURFACES    .ui-card (+ __head __body __foot __media __name __meta)  .ui-stats .ui-stat  .ui-kv  .ui-media  .ui-divider
 *   BUTTONS     .ui-btn (+ --secondary --ghost --danger --danger-ghost --quiet --dark --sm --lg --block, is-busy, disabled)  .ui-iconbtn
 *   FORMS       .ui-field .ui-label .ui-input .ui-select .ui-textarea .ui-hint .ui-error .ui-check .ui-switch .ui-input-group .ui-form-actions
 *   DATA        .ui-badge (+ state modifiers)  .ui-tablewrap .ui-table  .ui-progress  .ui-avatar  .ui-menu
 *   FEEDBACK    .ui-empty  .ui-skeleton + .ui-skel-*  .ui-note  .ui-toast  .ui-modal  .ui-more .ui-pager  [data-tip] (needs js/ui-tip.js)
 *   V3 ADDITIONS  .ui-back (back button)  .ui-kpi (tile)  .ui-icon (+ --sm --lg)  .ui-state (loading / error block)  svg guards
 *
 * ICONS: inline <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1.8" stroke-linecap="round" stroke-linejoin="round">.
 *   Sizes: 16px in buttons and badges, 18px in icon buttons and menus, 20px in the top bar, 26px inside a .ui-empty__icon, 48px at most in a drop area.
 *   Always give an icon svg a width/height attribute or put it in a sized wrapper: the guard at the end of this file stops an unsized one growing past
 *   1.5em in controls (and 48px in icon wrappers), but a size you set yourself is always better.
 *
 * Class names never use the words ad, ads, advert, sponsor, promo or banner: browser ad blockers hide those.
