Sends messages to Google Chat spaces via incoming webhooks, handling text, cardsV2, and threaded replies. Comes with TypeScript utilities for building cards and a complete widget reference, including decoratedText for key-value pairs, buttonList for actions, and collapsible sections. The formatting guide is legitimately helpful since Google Chat uses its own syntax (*bold*, _italic_) instead of standard Markdown, which trips people up constantly. Use this when you're scripting notifications, building status cards with actual structure, or need to thread related updates together. The card builder removes most of the JSON wrestling, and the known icon list saves you from hunting through Google's docs.
