WebVTT Parser and Validator

The `webvtt-parser` package provides a robust, specification-compliant parser and serializer for WebVTT (Web Video Text Tracks) files. Maintained by the W3C, it allows developers to programmatically parse WebVTT strings into a JavaScript object tree and serialize such trees back into WebVTT formatted strings. The current stable version is 2.2.0, and releases generally follow W3C specification updates or bug fixes, without a fixed cadence. Its primary differentiator is its direct adherence to the official WebVTT specification, making it a reliable choice for applications requiring strict compliance, such as browser implementations or media processing tools. It supports both Node.js environments via npm and browser environments through a UMD build.
