/*
 * DRE Linked Data — the "Linked open data" page block.
 *
 * Built on the DRE theme's token API (DRE-theme DESIGN.md and
 * docs/DESIGN-INTEGRATION.md). Every var() carries the theme's own value from
 * dre-tokens-fallback.json as its fallback — tests/DesignTokenTest.php holds
 * them to it — so the block still renders sensibly outside the theme. There are
 * no mode branches: the semantic tokens already resolve for light and dark.
 *
 * The theme's own `.button`, `pre` and table rules are reused, not restyled;
 * the rules here add the block's layout, panels, count tiles and format chips.
 * Layout follows the block's own width (container queries), because a page
 * block can sit in a full-width section or a narrow column.
