/* ============================================================
   DoseIQ — DESIGN SYSTEM
   Clinical · precise · quiet · trustworthy
   ------------------------------------------------------------
   PRINCIPLES
   1. Light is the default. Clinical means white space, not neon.
   2. One accent colour. Deep teal, reserved for Guru and primary
      actions only. Everything else is ink and hairline.
   3. Type does the work. Tabular numerals everywhere numbers
      are compared — a dosing chart that doesn't align is not
      a clinical instrument.
   4. Depth by hairline and shadow, never by glow.
   5. Motion is 160ms and invisible. If you notice it, it's wrong.
