/*
 * Shared CSS for theme-agnostic core blocks.
 *
 * Naming: BEM with double-dash variants — `.core-block--<slug>` is the base
 * class on every core block's wrapper element; `.core-block--<slug>--<variant>`
 * styles a specific variant (style, size, etc.).
 *
 * Themes opt in by `@import`ing this file from their own theme CSS entry.
 * Theme presets declared in `theme.json` override these defaults by emitting
 * the theme's own class string (e.g. `lc-btn lc-btn--primary`) instead of the
 * `core-block--<slug>--<variant>` fallback below — so themes that customise a
 * block fully own its visual treatment.
