A from-first-principles mental model: renderer architecture, the event loop, tasks vs microtasks, the input pipeline, what isInputPending actually queries, long tasks and Interaction to Next Paint (INP), and scheduler.yield() mechanics, culminating in why the common "yield only on input pending" pattern is broken and what the correct pattern looks like.

Build the macOS Drift screensaver from scratch, one concept at a time, ending in a real-time fluid simulation rendered as a grid of glowing line segments.

Lerps, Bezier equations, Bernstein polynomials, and why every curve is just nested interpolation.
