- Text fields are limited to100,000 UTF16 units each and400,000 combined UTF8 bytes; file fields have their own displayed limits. Combined output is at most4MiB. Processing stops after30 seconds; tool-specific bounds may be tighter.
- Generated source is a downloadable result and is not executed here. Inspection does not establish remote behavior, trust or standards certification.
