- review display: photos with lightbox, verified badge, pagination
- admin moderation: pending/approved/rejected tabs, bulk actions, nav badge
- SEO: JSON-LD AggregateRating and Review markup on product pages
- automation: review request emails 7 days after delivery (Oban worker)
- rating cache: avg/count fields on products, updated on approval
- fix file size validation in media test (10MB limit)
