- Around line 115-117: Update the branding update flow around
revalidateProgramPublicPages so inherited default-group propagation completes
before public-page revalidation is scheduled. Await the existing propagation
task before calling revalidateProgramPublicPages, or add a follow-up
revalidation after propagation completes, while preserving the current
conditional triggers.

Await inherited-group propagation before revalidation.
revalidateProgramPublicPages() defers revalidatePath() to after(), while default-group propagation runs in a separate, unawaited waitUntil task. If propagation is still pending when the response closes, an affected public page may render stale inherited data and repopulate its cache without a later invalidation. Await propagation before revalidation, or revalidate again after it completes.
