+/**
+ * v1.4.19 — Sys/Dia badge enum-mismatch regression guard.
+ *
+ * The mobile-list BP-type badge must check the canonical
+ * `BLOOD_PRESSURE_SYS` / `BLOOD_PRESSURE_DIA` enum values (matching
+ * `prisma/schema.prisma` and `MEASUREMENT_TYPE_LABEL_KEYS`). An earlier
+ * implementation checked `BP_SYS` / `BP_DIA` — short forms that never
+ * appear in the API payload — so the badge silently never painted on
+ * mobile. The desktop table was unaffected because it routes through
+ * `MEASUREMENT_TYPE_LABEL_KEYS[m.type]`.
+ *
+ * This guard renders the mobile list with one systolic + one diastolic
+ * row and asserts both labels show up.
