As Vue apps grow, I’ve noticed state management gets messy faster than expected, especially with things like:

• multi-step forms
• shared state across unrelated components
• async API states/loading/errors
• caching + optimistic UI updates

For smaller apps, local state and props/events feel fine. But in larger projects, I’m curious what patterns people actually prefer in practice.

Do you usually:

• keep most logic inside composables?
• centralize more aggressively with stores?
• split domain logic outside Vue entirely?

Not looking for a “one true way,” just trying to understand what has stayed maintainable for people building bigger Vue applications.
