/**
 * WebCreator - card grid (markup: docs/page-editor-blocks.md)
 *
 * Loaded only on pages that contain a card grid (div.wc-cards, see wc_block_assets()). No script.
 * Colours, radius, shadow and fonts come from the theme variables (docs/themes.md, 4 and 7), with fallbacks:
 *   card surface   --color-bg (the page colour; every ring colour of the contract holds on it) + --color-border
 *   text           --wc-text, quiet text --color-text-muted      button  --wc-primary / --wc-on-primary (like .btn-primary)
 *   ring           --wc-focus-ring        shape  --wc-radius, --wc-btn-radius, --wc-shadow
 * Layout: flex, not grid, so that an incomplete last row can be centred (data-wc-center="on"). Cards in a row are
 * equally high (the default; data-wc-equal="off" lets each card keep its own height). 1 column on a phone, at most 2 on a tablet.
