Templates that can only show text at the top\n * just always pass position=\"top\".\n *\n * Example — a data template (caption above a chart):\n *\n *   <TemplateText\n *     archetype={textArchetype}\n *     text={variables.title}\n *     progress={progress}\n *     sceneDuration={sceneDuration}\n *     width={width}\n *     height={height}\n *     position=\"top\"\n *     sizeRole=\"caption\"\n *   />\n *\n * Example — a media template (full-frame headline):\n *\n *   <TemplateText\n *     archetype={textArchetype}\n *     text={variables.headline}\n *     progress={progress}\n *     sceneDuration={sceneDuration}\n *     width={width}\n *     height={height}\n *     position=\"center\"\n *     sizeRole=\"headline\"\n *     beatIntensity={beatIntensity}\n *   />\n *\n * Note: `textArchetype` is destructured from props (a scene-level\n * field on `SceneTemplateProps`), NOT read from `variables`. Copying\n * the wrong pattern silently no-ops — the executor routes\n * `setSceneVariable(\"textArchetype\", ...)` to the scene-level field,\n * never into variables, so `variables.textArchetype` is always\n * undefined.\n */\n\nimport {\n  renderArchetype,\n  normalizeArchetype,\n  type TextArchetype,\n  type ArchetypeRender,\n} from \"../typography\";\nimport type { TypeTreatment } from \"../theme\";\nimport { renderWithEmoji, planTypewriterEmoji } from \"../emoji/emoji-text\";\nimport { Emoji } from \"../emoji\";\n\nexport type TextPosition = \"top\" | \"center\" | \"bottom\";\nexport type TextSizeRole = \"headline\" | \"caption\" | \"label\";\n\nexport interface SafeZone {\n  top: number;\n  right: number;\n  bottom: number;\n  left: number;\n}\n\nexport interface TemplateTextProps {\n  archetype: TextArchetype;\n  text: string;\n  /** Scene progress 0→1. */\n  progress: number;\n  /** Scene duration in seconds — drives entrance/exit phase scaling. */\n  sceneDuration: number;\n  /** Frame width in pixels (1080 in production, smaller in previews). */\n  width: number;\n  /** Frame height in pixels (1920 in production). */\n  height: number;\n  /** Where the text box sits in the frame.
