Medication Refill Tracker

A real medication tracker, not a checklist. Builds today's dose schedule from daily, weekday, or every-N-hours rules; decrements an exact pill count as doses are logged; simulates forward day-by-day for a real days-of-supply-left and refill date; tracks on-time vs late adherence and streaks. Multiple people/pets, JSON export/import. Zero dependencies, fully offline. Playwright-verified: every demo dose log matches an independent re-simulation exactly. (AI-assisted build; verified working.)
