Store/replace a brand's COMPLETE brand guideline on XeoRank WITHOUT touching any live site — works for ANY brand/platform (WordPress, Shopify, Wix, code, static, or not-yet-connected). This is the 'populate the XeoRank end' path — capture the design system even when you can't style the live site. Author the FULL guideline, not a thin kit — every section below is stored verbatim and rendered in the Brand Kit tab + the downloadable HTML guidelines doc: meta{name,tagline,description,version}; colors (primary/secondary/accent/text/bg/border + hover/active/subtle states + success/warning/error/info + any ramp e.g. brand-900..50) with colorMeta {name:{purpose}} for roles; fonts[] (per-slot family/weight/lineHeight/letterSpacing/transform); typography{heading,body,scale(H1–H6+body+small with sizeTablet/sizeMobile/lineHeight/letterSpacing),links{color,hover,visited,focus}}; buttons{radius,padding,typography,variants[]}; images{radius,opacity,shadow,hover}; iconography{grid,style,stroke,sizes,palette[]}; forms{...}; header{...}; footer{...}; identity{siteName,tagline,logo,favicon}; background{color}; layout{containerWidth,contentWidth,boxedWidth,widgetSpacing,sectionSpacing,breakpoints}; lightbox; transitions; woocommerce; accessibility{contrast[]}. To ALSO apply the Elementor-writable subset as the global theme on a connected WordPress site, use wp_set_brand_kit. site_id is the BRAND id from list_sites (NOT a WordPress site id).
