/*
   VSL IA — Styles
   Design Direction: ON-AIR AUTOCUE (Hard Rule #16 — new, no other tool uses it)
   ─ Broadcast-studio / teleprompter control-surface aesthetic.
   ─ Palette: studio near-black canvas + warm autocue reading glow (amber→warm-white)
     + on-air REC-red accent + graphite chrome + off-white read text; monospace timecodes.
   ─ Signature: the VSL renders inside a real TELEPROMPTER reading panel (large centred
     reading text + moving reading-line + REC dot + running timecode), beats laid on a
     RUNTIME TIMELINE RULER; an autocue/REC glyph on the gate.
   Distinct from Cinematic Storyboard (roteiros-ia), Spotlight Stage (slides-ia) and
   Checkpoint Terminal (mono phosphor console — this uses warm amber + REC-red, not green).
