/* v5-training.css — V5 Training & Resources page (internal agent knowledge base).
 *
 * Follows ATLAS design tokens (var(--*)) and the v5-listings / v5-showings page
 * pattern. No scroll at 1920×1080: the outer .tr5-page never scrolls; .tr5-body
 * handles internal overflow. Both light and dark themes covered via CSS
 * variables. Luxury real-estate direction: champagne accents, layered shadow on
 * hover, editorial card hierarchy, hand-crafted hover/focus states.
 *
 * Namespace: .tr5-* (distinct from the legacy .tc-* Training Center).
