Railway RRB Photo & Signature Boundary Checks

Railway recruitment servers strictly inspect file boundaries. Photos below 30 KB or above 70 KB trigger instant upload crashes.

Signatures must be signed with black ballpoint ink on plain white paper, measuring between 30 KB and 70 KB with 140 × 60 pixel resolution.
