   THE STORYTELLING COLLAB — SERVICE PAGES
   Currently: ai-seo.html

   Built on the tokens in colors_and_type.css. No new colours, no new families.
   Nav and footer rules mirror the static pages so this reads as one site.

   Static HTML on purpose. A page selling AI visibility that AI crawlers
   cannot read would be an embarrassment, and we have already made that
   mistake once on the homepage.
