 * skin compiler serves a server-generated CSS that overrides any subset
 * of these under a higher-specificity selector (e.g. body[data-skin]).
 *
 * This file MUST list every variable every component references. A
 * user-uploaded skin that omits a token will fall back to these values,
 * so the UI never breaks from a partial skin.
 *
 * Token naming: --lib-<section>-<key>. Sections match the default skin
 * JSON shape in apps/library/skins/default.skin.json.
