page limits
NIH enforces per-attachment page limits that vary by activity code and funding opportunity; the system checks many of them automatically.
How we handle it: Follow the Table of Page Limits in the specific funding opportunity. UploadPrep prepares compliant files but cannot enforce opportunity-specific page counts.
