Missing streaming / karaoke‑style highlighting for questions

In the interview player / live interview screen, the question text appears all at once with no indication of which part of the sentence the agent is currently speaking. I expected a streaming or “karaoke‑style” highlight that tracks the agent’s speech across the question text.

Steps to Reproduce

1. Go to an active interview session.

2. Start the agent and watch the displayed question while it is being asked.

3. Notice that the full question appears as static text, with no streaming or progressive highlighting.

4. Try to follow along word‑by‑word with the agent’s speech.

Actual vs Expected Behavior

Actual: The question appears as a static block of text while the agent speaks, with no visual cue indicating which part is being read aloud.
Expected: The full question should appear in a muted/gray style first, then progressively highlight (e.g., turning to black) in sync with the agent’s speech, similar to karaoke lyrics.

Additional Context (optional)

This is primarily a UX enhancement rather than a crash‑type bug, but it significantly affects clarity and perceived polish.
