/* builder.css — App Builder SPA (Design 042 §5.3 builder UI).
 *
 * Theme tokens ONLY (AI_CONTEXT rule 2 / Prime Directive #7): every colour comes
 * from a --color-* token so the surface works in light AND dark. The two themes are
 * declared as token sets on body.theme-light / body.theme-dark; builder.js toggles
 * the class and respects prefers-color-scheme on first load. Token NAMES mirror the
 * site's --color-* scheme so the builder reads as part of the same product. */
