Raw markdown view appends extra empty lines at the bottom of files

[ambient-code]

Category: bug / UX improvement

Summary

When viewing raw markdown (or any file) in the platform, extra empty lines appear at the bottom of the content. The original files do not contain these lines — the platform or UI is appending them.

Steps to Reproduce

1. Upload or create a file with no trailing empty lines
2. Open the file artifact in the raw markdown view
3. Scroll to the bottom
4. Result: Multiple empty lines appear at the end of the content that are not present in the source file

Expected Behavior

Raw file content should be displayed exactly as-is, with no extra lines appended.

Actual Behavior

Extra empty lines are appended at the bottom of the raw view regardless of the file's actual content. This has been reproduced with:

• Uploaded files that have no trailing newlines
• Files created within the platform

Notes

• The issue is consistent across different files, suggesting it is added by the platform rendering/serving layer, not the file content itself
• Verified by inspecting source files directly — they end cleanly with no trailing blank lines
