/* =========================================================
   Patient 360 — Patient OS
   Built to public/reference/brand-guidelines.md. Loaded after /index.css.

   The brief's green (#16C542) is not in our palette. --lime is the fill
   for the active state, the confirmed status and the live path; green
   TEXT is --lime-ink, because --lime on white is 1.28:1. Status never
   rests on colour alone — every state also carries a word (§34, §11).

   THE PRODUCT BOUNDARY IS THE POINT. Patient 360 provides context;
   Communication, Education, Journeys, Ticketing, Workflow Orchestration
   and Intelligence do the rest. So anything belonging to another product
   is drawn at .p3-ui.sm inside a bordered column with its own outbound
   link, never at the scale of the Patient 360 surfaces.

   Every class is prefixed p3- ; the reset weighs nothing (§14).
