# update_site_brand

Update ONE site's brand identity. This is per-site — unlike update_project, which fans the same values out to every site in the project. Editable: brandName, description, industry, targetAudience, tone, mainWebsiteUrl, ctaUrl, ctaTextOptions, market, marketCountry, marketDetails, products, keywords, topicScope, imageQueries. Arrays REPLACE the stored list — read with get_site_brand first and send the full array. topicScope is the trend-hunter niche anchor: topicScope[0] decides which trends the auto-article pipeline seeds from, so a stale value keeps producing off-brand articles after a rebrand — fix it here. NOT editable here (the call is rejected, not silently ignored): logoUrl/faviconUrl → update_site_branding; heroTitle/tagline/features/navLinks/packLabels → update_site_content; language → needs a re-enrich, since changing it does not re-translate existing copy.
