/* PeptiHealth.AI — personal health dashboard
   Direction: athletic and energetic. Dark stage, bold condensed numbers,
   rounded cards, pill navigation, brand gradients from the PeptiHealth helix.
   Every reading still shows its source on the left edge:
   teal-to-purple = Oura, orange-to-yellow = entered by you, dashed = planned, hatched = no data. */
