I took a screenshot of the QR fragment.

Wanted to zoom in, study the edges.

But when I opened the gallery...

there was no image preview.

Just this text under the file name:

glyph trace detected
entry unstable: observer not dormant
mirror proximity = HIGH

I tried to delete it.

My screen dimmed to black for 4.4 seconds.

When it came back, the image was gone—
but my camera roll had one new folder:
unnamed_0

It was empty.
