  "_readme": "The narration for every section. Scenes play in this order as slides. A scene shows the page section with the same id, or the one named in \"section\" (the five brain scenes share the brain section). Wrap key words in *asterisks* to highlight them in the caption (they are not spoken differently). A segment's \"brain\" value switches the 3D brain to that state when the segment starts; \"focus\" spotlights one of that state's labelled areas (use the label name exactly, e.g. \"Caudate nucleus\") while the segment is spoken, and \"focus\": null shows all of them again. After editing, run tools/generate-voice.mjs; it re-records only scenes whose text changed. A scene's \"sources\" (ids from the \"sources\" list below) are shown as \"Medical Sources\" in the top-right corner while it plays; clicking one opens its card. A segment's \"intent\" (0-100, optional \"intentMood\": drop / fight / won) moves the buying-mood meter beside the phone, and \"feeling\" names the emotion shown under the number. A scene's \"hold\" (seconds) keeps its last picture up that much longer before the next slide.",
