Key Themes from the discussion

Theme Supporting Quote
Licensing & Attribution "We've been very honest about our work being on top of BiRefNet... cc‑by‑nc is a protection against that." – snyy
Resolution & Scaling "We resize the opacity mask. That tends to scale better." – snyy
Open‑source Collaboration "Please do try, I would love nothing more!" – snyy

These three themes capture the main conversation points: concerns about license choice and credit, the technical ability to handle higher‑resolution images, and an invitation for the community to experiment and contribute.
