Generate an animated narrated explainer video (MP4). Claude writes a custom HTML animation page tailored to the topic, then the skill handles voiceover (free Edge TTS), recording (Playwright), and merging (ffmpeg). Use when the user says "make an explainer video about X", "generate an animated narrated video for [topic]", "create an explainer video". Output is a 1280×720 H.264 MP4 with synced narration.
