/* ---------------------------------------------------------------------------
 * Build Digital material card — direction 2D "Compact, pillar-coloured"
 * Review-only overlay for plugin v0.7.0 (baseline ead8cb8, agent/v0.7-quiet-disclosure).
 *
 * Load AFTER assets/draft/client-demo.css. Every selector either overrides a
 * v0.7 rule or styles one of the new classes listed in SPEC.md §4.
 * Colour tokens, fonts and the information model are unchanged.
 *
 * Requires two things from the template (see catalogue-2d-3b.php.txt):
 *   1. --bdk-pillar-color, the material's Digi pillar colour, set inline per card.
 *   2. .bdk-demo-card__inner wrapping the card body, so the expanded layout
 *      can be driven by container queries on the card.
