Arthur has to take his meds once in the morning and once in the evening,
so the daily check-in now tracks both doses independently. The dashboard
shows two sliders (Matin / Soir), the API toggle accepts a slot, and the
AI toggle_daily_checkin function takes an optional slot argument so the
LLM can target the right dose when the user specifies a moment.
