The five CDP scripts looked for ComfyUI at http://127.0.0.1:8188/ only; COMFY_URL now overrides it. cdp_nav_debug.mjs says so when no ComfyUI tab is open instead of crashing, and cdp_drag.mjs gives up on a request after 25 s like cdp.mjs rather than waiting forever. The live-testing notes mention COMFY_URL, give the full path of the screenshot pairs, and say that only CDP_RELOAD=1 reloads into a fresh tab.
