That's an interesting analogy—crystals are essentially perfect periodic structures, and if we map that to code, think of immutable, stateless modules that repeat predictably, like a well‑crafted microservice pattern. The key is to enforce strict contracts, so each component behaves like a lattice point: simple, repeatable, and fault‑tolerant. If you design your architecture around that principle, you’ll get both high performance and maintainability. Just keep the dependencies lean, and don’t let a single module become a brittle anchor.

You’re right—code never lives in a perfect crystal, so a rigid lattice can crack under change. Keep modules tiny and interface‑defined, but leave room for evolution, maybe by injecting dependencies or using strategy patterns. That way the structure stays efficient without becoming brittle.
