ComfyUI-SeedreamOfficialInput

ComfyUI built-in Seedream node downscales reference images to 2048x2048 on upload. This custom node calls the same ByteDance API, but uploads at official BytePlus limits:

longest side <= 6000px
total pixels <= 36MP
file <= 30MB (JPEG if PNG would be huge)
aspect 1:16 to 16:1

Output resolution is unchanged (Seedream 5.0 Pro still max ~2K / 4.19MP total pixels).

Uses the same Comfy Org / BytePlus API billing as the built-in Seedream node.

Seedream API has no mask socket and redraws the whole image. After generation, this node pastes the result back onto the original using the painted region:

white = keep Seedream pixels
empty / missing mask = pass the generated image through (full-image edit)
mask and mask_2 are OR-merged, so Painter + LoadImage masks both work
generated image is resized to the original
grow / blur soften the seam
