scraed 391ca9625f Trim the Qwen 2.1 section to a paragraph 
The section explained the VAE's channel count, the autogrow mismatch and the mask-size
measurements before saying where the example was. Keep what a reader needs: the model is
supported, transparency is inpainted too, and here is how to point it at your own picture.
The workflow's own note gets the same treatment.

"## Qwen-Image 2.1 + LanPaint, inpainting a picture with transparency\n\nThe source is RGBA and the edit is allowed to change the alpha, so the rebuilt sole gets\na new silhouette instead of just new pixels.\n\n`Join Image With Alpha` re-attaches the picture's alpha - `Load Image` hands it out on its\n`MASK` output rather than keeping it on the image. That mask is `1 - alpha` (1 =\ntransparent), which is what `Join Image With Alpha` wants, so it connects with no invert.\n\nThe mask is a separate greyscale file, white = repaint, and it is kept modest here (about\n16% of the frame). LanPaint anchors everything outside the mask to the original on every\nstep, so a mask covering most of the picture leaves the model without context."
