/* assets/components/market-selector.css — 7-market selector widget (P3 Phase 1A).
 *
 * Companion to assets/components/market-selector.js. Pure widget: page
 * injects regions, regionToCountries mapping, current value, onChange.
 *
 * STRUCTURE:
 *   Flat grid of region rows. Each region row is a checkbox + label. When
 *   a region with >1 country is checked, its country sub-grid renders
 *   INLINE below the region row. Unchecking the region removes the sub-
 *   grid and clears its countries. No accordion, no expand/collapse — the
 *   country detail's presence is driven entirely by the region checkbox.
 *
 *   Multilateral region (zero countries in config): single checkbox row,
 *   no sub-grid. Vendor IDs for multilateral bodies live in the wizard's
 *   Step 4 code-fields section, NOT in this widget.
 *
 * Used by: trial-setup.html Step 3, profile-update.html, future
 * subscriber-portal.html. Data source-of-truth: bidclarity_regions.py.
 *
 * Palette per CLAUDE.md: accent #00D4AA (selected state); F0F6FF body;
 * 9BBBD8 secondary; 7A9CC0 muted.
