Theme Name: Cerebra
Theme URI: https://cerebra-ai.on-forge.com
Description: Theme for the CEREBRA-AI project site. Implements the design in the
  CEREBRA-AI content package v1.1 (preview/preview.css and wordpress/cerebra-brand.css).
  Page content supplies its own H1 and its own EU funding section, so neither the
  page template nor the site footer repeats them.
