 * --------------------------------------------------------------------------
 * Owner: main-domain offers UI/UX redesign — Batch 3
 *   (plan: ~/.claude/plans/main_domain_offers_uiux_redesign.md §5/Batch 3)
 *
 * Scope: side-by-side feature comparison table consumed by
 *   offers_render_comparison_table(). Read on offers.php right after the
 *   plan-strip, and on landing.php inside a collapsible <details> labelled
 *   "Vergleichen".
 *
 * Boundaries
 *   - Reads from theme_a/tokens.css ONLY (--compare-*, --space-*, --primary,
 *     --primary-rgb, --surface, --surface-2, --border, --text, --text-rgb,
 *     --text-strong, --muted, --shadow, --radius, --plan-card-radius,
 *     --focus-ring). No raw hex.
 *   - All inset / padding / margin / border properties use logical axes
 *     (inset-inline-*, padding-block, padding-inline, margin-inline,
 *     border-inline-*) so RTL works without overrides.
 *   - prefers-reduced-motion disables open/close summary animations.
 *   - @media print neutralizes the sticky column + scroll-snap so the
 *     printed sheet shows the full table grid.
 * ========================================================================== */
