What that means in practice
Real-time interfaces
WebSocket pipelines, normalised state, live data that stays coherent under load.
Data-dense UI
Trading desks, 250-field constraint matrices, charts that survive being looked at closely.
3D & visualisation
Three.js and React Three Fiber, coordinate systems, camera behaviour.
Design engineering
Figma to production, OKLCH colour systems, motion that has a reason.
