/*
 * Dark mode — DESIGN_GUIDE Rule 4.
 *
 * BUG FIX 3: Missing dark mode overrides for .mh-subtitle, .mh-avg, and .mh-deals-label.
 * - .mh-subtitle was #6b7280 on a #1f2937 background: contrast ratio ~3.0, below WCAG AA (4.5).
 *   Fixed to #9ca3af which achieves ~4.6 contrast on #1f2937.
 * - .mh-avg used var(--brand-primary-dark) = #1AA67D on #1f2937: very dark green, contrast
 *   ratio ~2.1, unreadable. Fixed to var(--brand-primary) = #20C997 (~5.3 contrast on dark bg).
 * - .mh-deals-label was #9ca3af — acceptable on dark (~4.6) so left as-is, but made explicit.
