   Uses the 2026 ECI teal identity as specified in the programme brief:
     Warm Cream #F7F3EA (background) · Deep Teal #005E66 (serious sections)
     Primary Teal #007C89 (buttons, highlights) · Warm Amber #E88A2A (small
     accents only) · Charcoal #2F3437 (body text)
   Everything is under .amb so the rest of the site (still deep green and
   terracotta) is untouched. Shared header and footer keep the site identity.
