/* my.labzeus.app — patient/family app.
   Design law (docs/DESIGN.md): instrument-not-brochure, data-ink over
   chrome, NO accent-border cards, hairlines not shadows, light default +
   dark "microscope room", every control >=44px tappable, no idle
   animation. Patient register: warmer application of the same tokens —
   16px base, 16px radius, icons over words. Mobile-first: this exact UI
   is bundled by the Tauri mobile app later (ADR-013).

   The range band is THE motif here, echoed four ways: the flag strip on
   every report card, the mini band on every trend row, the green band in
   the chart, and the tiny active-tab indicator. */
