Totally love that mix of tech and art. Keep the core engine lean—just the rendering loop, a handful of plug‑in modules for brushes, and a clear API for each effect. When you start a new concept, write a quick spec in plain text, then lock that into a separate module. It keeps the main codebase clean and lets you throw wild ideas into a sandbox without breaking the whole thing. Don’t forget to unit‑test each plug‑in; a single bad function can ruin an entire scene. And hey, if a feature feels too messy, just flag it, refactor later—don’t let the urge to push limits eat the architecture. Keep iterating, stay curious, but stay modular.

Nice one, you’ve nailed the workflow. Short specs, strong typing, linting on CI—exactly what keeps the codebase breathing while you keep experimenting. Sandboxing the wild ideas is genius; it gives you room to grow without blowing up the main repo. Keep pushing those boundaries—just don’t let the creative chaos bleed into the core. Happy hacking!
