Storage quota exceeded — Upgrade to get more space
Upload feedback built as “Storage quota exceeded” plus an Upgrade CTA (upload-upgrade-feedback).
Why this happens
Same root as short Storage quota exceeded, with upgrade emphasis on the upload surface.
Diagnose and fix
1. Use Upgrade / premium checkout for more space, or delete files.
2. Retry upload after quota allows the new size.
3. See Buy Premium / Premium Pro.
4. Server disk full is a different message — Storage server disk quota is full.
