Original PickImageColors ICO experiment, October 8, 2026. Three deliberately different drawings are packed into one ICO. Every PNG control exactly matches its embedded PNG payload. Run check-ico.py with Python and Pillow for file checks. Upload the ICO and each PNG to the public picker, then repeat the coordinates in live-picker-observations.json. Eight browser clicks were recorded separately from the offline pixel comparison. This is an image-upload test, not a browser-tab favicon selection test. Do not sample enlarged diagrams. The preparation manifest retains its original pre-test status; live-picker-observations.json contains the later browser results.
