Photopea Mockup Scene Stage: product workflow and lessons learned

What I learned building Photopea Mockup Scene Stage

The workflow problem

Creators otherwise search for separate PSD mockups, replace Smart Objects, adjust light and placement, and export each scene repeatedly.

The result

Sync one open design, art-direct four live scenes together, and export gallery poster, tablet, box, and card PNGs in one ZIP.

Verification

I tested the finished build in its actual target application, including the main workflow, output and documented limits.

I built the product; details and the tested package are here: https://dat398.gumroad.com/l/ebefn?utm_source=devto&utm_medium=community&utm_campaign=photopea_mockup_scene_stage&utm_content=launch
