Burnt Receipt

Inspect what survives after a perfectly valid PNG says it is finished.

THE TICKET

Brief

A one-pixel receipt preview renders normally, but its file is larger than the PNG structure accounts for. Locate and unpack the trailing evidence.

Objective

Find the end of the IEND chunk, identify the appended stream, and recover its note.

Container
valid PNG + trailing bytes
Clue
IEND is not EOF
Tooling
browser inspector included

The preview renders. The byte count still looks wrong.
