Frame: drop in a screenshot, get an image worth posting

Frame puts a screenshot on a backdrop, inside a browser window, a phone or a plain rounded edge, with padding, shadow and a ratio for where it is going (16:9, 1:1, 4:5, 1.91:1, 9:16). Paste with Cmd+V or drop a file, press S to shuffle looks, then download a PNG or copy it. It all runs in your tab; nothing is uploaded. One limit: 2x enlarges a small screenshot rather than adding detail, so use 1x for those. Frame your next entry and tell us which backdrop is missing.
