JPEG, PNG, WebP — max 10MB

Output is always PNG to preserve the embedded data. Original file is not modified.

How it works under the hood:
1. Your GENID is encoded as "GENID:XX12345\0" (null-terminated)
2. Each character's bits are written into the LSB of R, G, B channels
3. A SHA-256 hash of the stamped file is sent to Polygon as transaction calldata
4. The record is also saved to Supabase for fast public lookups
