Splits a property's search performance into BRANDED and NON-BRANDED using the branded keywords saved on the property (set them with update_site; a keyword wrapped in slashes like /acme ?corp/ is treated as a regex, otherwise it is a case-insensitive substring). Returns totals, the branded share of clicks, a daily clicks trend for both sides, and the top queries on each side, with optional comparison-period totals. nonBranded is the property total minus branded, so the two sides add up to the property total (total) and brandedClickShare is branded clicks over that total. Search Console leaves anonymised queries out of any query-filtered read, so they cannot be matched against the keywords; they are rare, long-tail searches, counted in nonBranded and also reported on their own as anonymized. topNonBrandedQueries lists named queries only. Returns notConfigured (not an error) when the property has no branded keywords yet. Served from the GSC Wizard ClickHouse warehouse when available, otherwise the live Search Console API (see dataSource). Date range is optional: omit startDate/endDate to analyze the last 28 settled days (data lags ~2-3 days).
