/**
 * Minerva CSS Custom properties
 * ----------------------------
 * Please be aware that these properties are accessible via *any* client-side code.
 * These variables should mirror Codex design token names and values:
 * https://doc.wikimedia.org/codex/latest/design-tokens
 * Only include properties that are required for client-side modification.
 *
 * @private - Currently, these variables are only intended for use by Minerva,
 *            however, they are designed to mimic the naming convention in Codex tokens
 *            in order to facilitate an eventual migration to a centralized source.
 * @experimental
 * @since February 2024 (MediaWiki 1.43)
 * This file is kept separate from the skin.less to avoid the side effects of CSS variable conversion
 * that occurs to LESS variables when importing mediawiki.skin.variables.
 * We import mediawiki.skin.defaults to obtain the original unmodified values for these CSS variables.
