Validation: basketball-api#275 — Superseded by #752 (blast endpoint)
Verdict: PASS (superseded)
Board item #735 ("Complete contract reminder email: branding fix, validate, blast") is superseded by board item #752 (basketball-api#295: Admin blast endpoint /email/blast). The new ticket covers branding via MJML templates (#750) and blast delivery (#752), making this compound ticket redundant.
No completed implementation against this ticket. Moved to done as superseded during 2026-04-03 email architecture overhaul.
