/* PURPOSE: Datum website additions on top of the shared StratifAI legal page styles (legal.css).
   CONTEXT: Used by the Pricing, Terms, Privacy and Refunds pages on datum.stratifai.solutions.
   HOW IT WORKS: adds the Datum header, tables for the policies and the pricing page layout.
   DEBUG: nothing here changes legal.css; remove this file and the pages fall back to the plain legal look. */
