src/transparency-iframe.html is a tiny html+body=transparent stub we serve at /transparency-iframe.html so dev hosts (and future debug tools) can include it via iframe to confirm that cross-origin iframe transparency is working in the target browser without involving any of the Artstr embed JS. Validated end-to-end: - srcdoc iframe → magenta shows through ✓ - cross-origin minimal page → magenta shows through ✓ - cross-origin Artstr embed → magenta shows through the Computer_Icon's transparent ring ✓ What looked like opaque white on the stress-test host was the artwork's natural fill + the host's pink/yellow checker reading as noise rather than see-through. Magenta on a flat backdrop made the transparency unambiguous.
