Pure client-side format parsing, never AI: blocks are split on blank lines and each block must have a sequence number, an HH:MM:SS,mmm --> HH:MM:SS,mmm timing line, and at least one text line. Timestamps convert to WebVTT HH:MM:SS.mmm (dot decimals); CRLF line endings are normalized; dot decimals and missing sequence numbers are accepted with warnings; cues with end time at or before start time are dropped as errors; overlapping cues are kept with warnings; all unicode text is preserved byte-identical.

Good to know
- SubRip has no formal spec; parsing follows the widely-observed convention (numeric sequence, HH:MM:SS,mmm --> HH:MM:SS,mmm timing line).
- Dot-decimal timestamps are accepted with a warning even though they are WebVTT style, not SRT convention.
- Cues with end time at or before start time are dropped as errors — the converter never invents replacement timings.
- Input is capped at 2,000,000 characters to protect the browser; unicode text is preserved byte-identical.
How it works

Timestamps convert to WebVTT HH:MM:SS.mmm (dot decimals); CRLF line endings are normalized; dot decimals and missing sequence numbers are accepted with warnings; cues with end time at or before start time are dropped as errors; overlapping cues are kept with warnings; all unicode text is preserved byte-identical.
Examples
Converts with zero errors or warnings; cueCount is 2.
Dot decimals are accepted with a warning, non-sequential numbering is flagged, and the overlap is reported.
