Implements a Result type (similar to Rust's Result) for explicit success/failure handling without exceptions. Provides Ok and Err variants with map, unwrap, and error propagation methods. Self-contained and reusable across any Python project.

Defines a BackgroundJob class that runs a callable in a separate thread with progress callbacks, cancellation support, and error handling. Uses threading.Event for clean shutdown. Reusable for any long-running task that needs UI progress updates.

Provides RateLimiter and SpeedLimiter classes for controlling call frequency and data throughput. Uses time-based windows and token bucket patterns. Self-contained and applicable to API rate limiting, UI debouncing, or stream processing.

Collection of reusable Dear ImGui helper functions: tooltip_if_hovered, centered window positioning, disabled scope context manager, primary/destructive button styles, and section card wrappers. Reduces boilerplate and ensures consistent UI patterns across the application.

Implements a section_card context manager that wraps ImGui child windows with a header, optional collapse/expand, and consistent styling. Provides a reusable UI pattern for grouping related controls in settings panels.

Defines the abstract base class for funscript transformation plugins with parameter schema validation, preview generation, and a global PluginRegistry singleton. Demonstrates a clean plugin system that can be extracted for other transformation pipelines.

Implements an asynchronous YOLO inference worker with a bounded queue, background thread, callback-based result delivery, and automatic batch size probing. Handles model warmup and fallback. Reusable for any real-time object detection pipeline that needs non-blocking inference.
