The design for a language app with 100K+ users has been in the dev team's hands for weeks. They haven't messaged me once to ask what something should be. That's the point of a proper handoff. Every version of every screen already drawn, including the ones nobody wants to think about. Every color and spacing tied to a rule the whole product runs on. Naming that matches what the engineers already use. If a dev has to ask what a value should be, the file wasn't ready.
