- Add 1536x864, 864x1536, 2048x1152, 1152x2048, 2560x1440 to the size dropdown. 2560x1440 is the OpenAI cookbook's recommended upper widescreen reliability boundary - Note that sizes above 2560x1440 are experimental and the max-edge rule is strictly <3840 (3840x2160 is out, use 3824x2144 instead) - 1920x1080 is invalid because 1080 isn't a multiple of 16 — captured in AGENTS.md alongside the full constraint set so future agents stop proposing it
