Provides a reusable DOM-to-markdown conversion utility (serializeNodeToMarkdown) that handles various HTML elements (headings, lists, code blocks, etc.) with configurable options. Self-contained, dependency-light (only requires marked), and extractable for any project needing DOM content conversion to markdown.

Implements smooth scrolling with custom offset to avoid fixed headers (smoothScrollTo). Uses requestAnimationFrame for performance and accepts offset parameters. Isolated utility with no internal dependencies, making it reusable in any web application needing smooth scrolling adjustments.

Handles file downloads from Blobs with automatic MIME type detection and filename sanitization. Simple, self-contained function (download) that creates object URLs and triggers downloads. Zero dependencies, easily portable to any frontend project requiring client-side file generation.

Generates sanitized, dated filenames for exports (getExportFilename). Combines chat title, format, and timestamp while removing unsafe characters. Pure function with no dependencies, suitable for reuse in any export-heavy application needing safe filename creation.

Event-based toast system that listens for custom 'scroll-pro-toast' events to display notifications. Decoupled from calling components via document events, allowing fire-and-forget usage. Self-contained UI component with enter/exit animations, easily adaptable to other projects needing lightweight notifications.

Standard React error boundary component that catches errors in child components and displays a fallback UI. Follows React best practices with getDerivedStateFromError and componentDidCatch. Highly reusable across any React application for graceful error isolation.
