 * Count how many of the 4 E-E-A-T signal categories the page satisfies.

 *  1. About-page link — a same-host href containing /about
 *  2. Author identity — any authorSignals field present
 *  3. Published date — page.publishedDate set
 *  4. Transparency text — "sources:", "references:", "last updated", etc.
 *     in page.contentText (NOT raw HTML, to avoid footer/JS false positives)
 *
 * Exported so value-add can reuse this without duplicating logic.
