- Concatenate all paragraphs + transition hint into one TTS call per slide
→ natural prosody, zero gaps within a slide
- Pre-fetch next slide's audio during current playback → seamless transitions
- Advance slide during transition phrase ("Let us look at...")
- Pause/resume without destroying audio → instant continue
- Subtitle display synced to playback position via timeupdate

from it. Move SLIDE_ORDER to lib/slide-order.ts (no 'use client') and
re-export from useSlideNavigation for backwards compat.

causing it to bail out. Now sync stateRef immediately before advance.
