Splits the single hardcoded-feeling course template into hero,
credibility, curriculum, and repeat-CTA sections, each rendering only
when its front matter fields are set. The enroll form (and its
EEC-trigger JS) moves into a reusable partial so it can appear more
than once on a page without id collisions.
