- Delete scripts/setup-r2.sh (Cloudflare R2 is not the storage provider)
- Create scripts/setup-b2.sh that documents B2 CDN setup:
- Prints B2 bucket endpoint (us-west-002)
- Prints CNAME target for b2.aicodebattle.com
- Verifies B2 credentials when env vars are set
- Informational/verification-only (no destructive operations)
- Update scripts/cloudflare-setup.sh:
- Remove R2 bucket creation steps
- Add note that B2 setup is separate (see setup-b2.sh)
Acceptance criteria met:
- scripts/setup-r2.sh does not exist
- scripts/setup-b2.sh exists, is executable, and runs without error
- No references to setup-r2 remain in scripts/
