per-file size ceiling
The portal FAQ states attachments must be under 50 MB; this wording was captured from the FAQ text as archived by a tender aggregation service rather than read live. Third-party Horizon guides separately cite 10–20 MB per proposal part.
How we handle it: Keep every attachment comfortably below 20 MB where possible and treat 49,999,999 bytes as the hard per-file boundary; confirm the System Requirements page for the specific procedure before submitting.
