Build an animated coding-pattern reel (MP4) for HackProduct / WebAlgos. Teaches interview patterns — Two Pointers, Sliding Window, Binary Search, BFS/DFS, DP, and more — through motion and sound, designed to build AI-engineering judgment, not just memorization. Use this skill whenever Raja asks to build, render, or re-render a pattern reel, says "do the next pattern", "make a reel for X", "dark mode video", or anything involving producing an MP4 animation that teaches a coding pattern. Covers the full pipeline: Pillow frame rendering → procedural audio → ffmpeg H.264 MP4, always in dark mode, always 24fps 1080×1920.
