No AI words in the UI

Decision

The UI never talks about AI, models or confidence. Every number, bar and color says something about the user's food and day.

Why

Set by the owner on 2026-09-26 while choosing the home screen cards: "End user does not care what is AI, what is confidence."

Impact

• Labels, badges and charts use food words ("unknown", "guessed", "you said"), never "AI", "model" or "confidence".
• Internal names like the confidence tints in AGENTS.md stay in code only.
• See confidence for how the app decides what to ask.
