};

type DemoPacingConfig = {
  pace?: 'tight' | 'normal' | 'slow';
  chapterMs?: number;
  pulseMs?: number;
  afterClickMs?: number;
};

Defaults: empty personas, empty layout, empty pacing (pace: 'normal' when resolved), artifactsDir = /opt/cursor/artifacts (DEFAULT_ARTIFACTS_DIR), startPath = /.

Pacing is three teaching beats. pace scales them (tight 0.75, normal 1, slow 1.4). Explicit chapterMs / pulseMs / afterClickMs win. After-click default is 500ms on video and 700ms on headed stills. Per-call overrides: demoFocus(..., { chapterMs }), demoClick / fillField / fillShown / demoClickAndWaitUrl{ pulseMs, afterClickMs }.

personaStyle returns FALLBACK_PERSONA_STYLE when the id is unknown.
