/*
 * hub-components.css
 *
 * SharedUI partial component styles for vertical hub pages (Stage 4.0.1
 * partials: _HubProductPicker, _BotAgentComparisonTable, _PricingCardsBlock).
 *
 * Architecture: vertical-agnostic — uses only --brand-primary /
 * --brand-primary-light (set per-vertical by _SharedLayout :root) +
 * Bootstrap 5.3 built-in tokens (--bs-*).
 *
 * Loaded after vertical-specific CSS (e.g. medical.css) and after
 * full-footer.css. Unique .sb-* namespace prevents conflicts.
 *
 * Stage 4.0.6 — first stylesheet for SharedUI partials.
