Join puts a fixed cast note in front: \"TTS the following conversation between Tilly and Rotor\", which voice goes with which character, and \"Do not read the speaker names aloud\". Gemini 3.1 Flash TTS reads the whole thing as a two-person scene. Keep the cast note's wording close to this; when it was rephrased as \"a lively radio play\", every line came back in one voice. Rename the characters in both the idea and the cast note. Inspired by @jeffreyabrick's two-voice radio play (https://x.com/jeffreyabrick/status/2113269680702156843).",
