/* Iris — v0.12
 *
 * A clinician reads this between patients, so the job is information design
 * rather than decoration: what is dangerous has to be visible before anything
 * is read. Allergies sit above everything, severity carries colour, and an
 * out-of-range result is legible without checking the reference beside it.
 *
 * The palette is cool and desaturated on purpose. Red and amber are reserved
 * for clinical severity and are never spent on branding or chrome, so that when
 * something is red it means something.
