v8.7 (1) — TyG Metabolic Health card + progress tracking

[2026-06-10 v8.7 (1)] Smarter lab insights and progress tracking.

• TyG Index card. When a panel has triglycerides and fasting glucose, you get a TyG insulin-resistance reading with a color-coded gauge and a plain-English read — plus a normal / elevated / pre-diabetic / diabetic glycemic status from glucose and HbA1c.
• Weight progress photos. A private before/after photo timeline alongside your weight log.
• Lab comparison share card. Turn an improvement between two lab panels into a clean, shareable card.
