Most teams treat documentation like something you do at the end.
But that’s usually where things start to fall apart.
If a decision only lives in a file, or in someone’s head, it gets reinterpreted over time.
People make small changes, fill in gaps differently, and things slowly drift.
Documentation is what keeps that from happening.
It’s how design actually becomes usable by other people, not just something that looks right once.
If it’s not documented, it’s really hard to keep it consistent.
