/* PKB Group Ads Dashboard — v2 design system

/* Part 57 §8.2 — global fix for the recurring [hidden] specificity bug. Any
   component that sets `display: flex/grid` beats the UA default
   `[hidden] { display: none }` on specificity, so `hidden` fails silently on
   whichever component gets the treatment next. Fourteen per-class overrides
   had accumulated (two with comments saying "same issue already fixed
   elsewhere") — plus the idle-jobstrip artefact behind the Ask AI launcher
   (§8.1) and a left-edge phantom (§8.4). One high-specificity rule closes
   all of them and stops the file from accumulating any more. */

 * main, numbers) and only 4 on By-Landing-Page (no checkbox — landing pages

 * the markup. `flex-wrap` also means the numbers block naturally drops to
 * its own full-width line on narrow viewports without a separate
 * grid-template-columns re-declaration at the breakpoint (the old mobile
 * override rewrote the template outright — a sign the base layout wasn't

/**
 * Part 16 Item 3 — mobile bottom sheets. One shared pattern (comma-grouped
 * selectors, identical rule bodies — not three copy-drifted blocks) applied
 * to the three named surfaces: Export Center, the tag picker (shares
 * .notes-modal-overlay/.notes-modal with the ad-notes modal, which is
 * deliberately NOT in scope here — targeted by #tag-modal-overlay's own ID
 * so the plain notes modal stays a centered dialog, unchanged), and compare
 * mode. Desktop behavior (centered dialog) is completely untouched — this
 * block only exists inside the media query. Same 560px breakpoint as Part
 * 12's calendar modal, for one consistent "mobile changes shape here"
 * threshold across the app. Slide animation already respects
 * prefers-reduced-motion for free via the global rule further up this file
 * (animation-duration forced to ~0 for every animated element site-wide);
 * Escape-to-close, click-outside-to-close, and role="dialog"/aria-modal are
 * all pre-existing behavior on every one of these three, untouched by a
 * pure-CSS layout change.
