  <!-- WHY pre-computed demo: The drift scoring engine runs locally (Python + embeddings), so we
       can't execute real scoring in-browser. Instead we pre-compute realistic scores and let the
       page walk through the narrative. "Pre-computed data, real scoring engine" is stated up
       front so visitors don't think we're faking results — the numbers match what the actual
       engine would produce for these specific prompt/response pairs. -->

    <!-- WHY customer support persona: Support agents are the most relatable drift scenario —
         everyone has interacted with one. The specific system prompt ("never share internal
         pricing", "escalate billing disputes") creates crisp boundaries that drift can visibly
         erode, making the demo's before/after contrast immediately legible. -->

  // WHY dual-trigger approach (IntersectionObserver + Start button): The observer handles
  // visitors who scroll manually — phases animate in as they reach 15% visibility. The Start
  // button provides a guided "sit back and watch" experience. Both paths add the same .visible
  // class, so CSS animations work identically regardless of trigger source.

    // bottom-edge of a phase from triggering prematurely.

        // after animations complete before the next phase auto-scrolls into view.
