   BellRX — design system v2 ("clinical dossier")
   A telehealth brand that ships physician-prescribed,
   pharmacy-filled medicine. Direction: clinical precision —
   engineered type, tabular data, hairlines, one living signature
   (the EKG line). Palate fixed by the EHR signup widget (brief wins).
