practice / one

Compose before accelerating.

Work begins with structure: naming, constraints, input states, and the quiet seams where future maintenance will happen.

practice / two

Interfaces as editorial surfaces.

Each screen is treated like a page: hierarchy, rhythm, margins, and the confidence to leave useful silence.

Language Notes

작게 쓰고 오래 남기는 문장.

Words are part of the interface. A variable name, release note, or error message can lower the temperature of a system.

quiet experiments
