Description

If importing a .png with background transparency, the resulting sketch (jpg) produces a black background, making the sketch potentially unusable.

png -> sketch -> jpg

Likely this is a great reason to reconsider the .jpg output format for the sketch picker, likely to .png for transparency support.
Note: .jpg does not support transparent backgrounds.

No files or tests are named. Begin at the sketch picker’s PNG import and sketch-to-JPG conversion path, then verify behavior with transparent and opaque inputs. Done means transparent content is preserved without an unintended black background, with the chosen output format handled consistently.
