/* AnswerHatch v1
   Modern product-led SaaS shell, so the page reads as credible to buyers
   arriving from the incumbent AI-answers vendors. The distinctiveness is the
   refusal demo and the receipts identity, not the styling.

   One accent colour, and it means one thing: a source exists. Where there is
   no source, the accent is absent and the slot is ruled empty. */
