As a user, I want to download a 35MB file quickly and reliably, with clear progress indicators, so I can use the content without interruption. Target Size:
Knowing this will help me refine the UI and technical constraints.
Pre-compress the file using efficient methods (e.g., ZIP, GZIP) to keep it well within potential infrastructure limits (e.g., maximum attachment sizes of 25MB-50MB in some systems).
If the connection drops, show a clear "Download Failed" message with an active "Retry" button rather than a generic error.
