/*
 * Book Buddy Connect — card grid for courses and events.
 *
 * Everything is namespaced .bbc- so a theme's own rules cannot reach in, and
 * nothing here styles a bare element selector, so these cards cannot leak out
 * into the rest of the page either.
 *
 * The palette is the Book Buddy Academy site palette: cream page, white cards
 * on a warm hairline border, deep navy type, gold accent. Colours come from
 * custom properties on .bbc-wrap, so a page that needs a variant overrides
 * those values and touches nothing else.
 *
 * There is deliberately NO dark-scheme block. These cards are a fixed part of
 * the brand's light design; letting the visitor's OS setting repaint them made
 * them stop matching every other section on the page.
