# CDN cache rules + purge (P7.FE.01)

## Cloudflare (recommended)
- Cache static `/build/*` long TTL
- Bypass cache: `/cart`, `/checkout`, `/account`, `/admin`
- HTML: cache with short TTL + tag purge on product update

## Verify
1. Update product title in admin.
2. Purge tag / URL.
3. Confirm edge serves new title within TTL.
