   GLP 1 Tracker App - "Warm Paper" design system
   The app's own palette, expressed as a website: warm paper,
   quiet ink, periwinkle accent, and the metric colors used for
   protein / water / weight. Self-contained: no external fonts,
   no CDNs, no trackers. Light-first with a native dark mode,
   both generated from BrandPalette.swift.
