We'll stuff this about as much as the program can, with incompressible random binary data:
65,536 64k.bin 2025 Oct 11 19:27:33
131,072 128k.bin 2025 Oct 11 19:28:01
262,144 256k.bin 2025 Oct 11 19:28:29
524,288 512k.bin 2025 Oct 11 19:28:53
total:
983,040 bytes
With bScatter turned on:

Definitely grainy, but on average colors are preserved, and nuances of shading can be seen.
With bScatter turned off:

Zones of phantom colors are visible, but the most glaring problem is a posterization of blocks of brightness with sharp lines dividing them.
OK, that was stuffing an extreme amount of data. Let's push in a little less and see how it looks.

This looks almost normal.
With bScatter turned off:

Posterization of brightness is still clearly visible, as are patches of phantom colors.
All of the above embeds can be extracted using password "abc" (3 letters, no quotes).
