Provides bit-level operations (set, clear, test, count) with AMD64 assembly acceleration. The pure Go fallback ensures portability. This is a self-contained utility that can be extracted for any project needing efficient bitmap operations.

Implements 4x4 matrix operations with compile-time float32/float64 selection and SIMD assembly for AMD64 and ARM64. Includes transformation matrices, projection, and quaternion conversion. Demonstrates high-performance math library design with platform-specific optimizations.

Core physics constraint solver using Jacobian rows and sequential impulse solving. Provides reusable helper functions for world anchors, relative velocity, effective mass, and impulse clamping. This pattern can be extracted for any rigid body simulation requiring constraints.

Generic fixed-size object pool with thread-safe acquire/release. Used for physics shapes and other frequently allocated objects. Demonstrates a clean, reusable pooling pattern that reduces GC pressure in game engines.

Generic event system with typed event IDs, add/remove/execute methods. Supports both void and argument-carrying events. This is a self-contained observer pattern implementation that can be reused in any Go application needing decoupled communication.

Generic tween system with 30+ easing functions, duration, delay, and completion callbacks. The Tweener manages multiple tweens globally. This is a standalone animation utility that can be extracted for UI or game animation needs.

Binary archive format with XOR obfuscation, CRC32 verification, and index-based random access. Supports reading and packing. This is a reusable pattern for bundling assets into a single file with integrity checks.

Undo/redo history system with transactions, lockable additions, and command grouping. Used extensively in editor workspaces. This is a clean implementation of the memento pattern that can be reused in any application requiring undo/redo.
