Limits

Worker API shape matches the R2 Workers API. Local quotas come from ocd [r2]. Live numbers come from ocd capabilities --json. Embedded defaults include:

Item	Default
max_object_bytes	512 MiB
max_concurrent_uploads	4
max_concurrent_downloads	16
max_staging_bytes	2 GiB
operation_timeout_ms	30000

This is not Cloudflare's 5 TiB object size or unlimited storage plan. The S3 provider's own limits still apply.
