+/// Everything the dashboard's Chart tab needs in ONE payload.
+///
+/// The demographic fields at the top are the patient header; the five lists
+/// below are the chart panels. dashboard.js reads chart.conditions.length,
+/// chart.allergies.length, etc. — so these lists must ALWAYS be non-null,
+/// even when empty. That is why each one is initialised to an empty list
+/// instead of being left null.
