Behavior and limitations

• Each cue is one translation unit with a sequential key such as vtt.0001.
• Cue identifiers, timing, positioning, and settings are preserved. Timestamps and named cue identifiers supply context.
• WEBVTT headers and NOTE, STYLE, and REGION blocks remain unchanged.
• Writeback keeps cue counts aligned with the template. Review reading speed and line length separately.
