/* =========================================================
   Dr John Mackintosh — Respiratory Physician, Brisbane
   Design tokens for a warm, approachable patient-facing feel:
   calming medical teal + soft green, warm off-white grounds,
   soft rounded "soft-UI" cards with gentle shadows, and
   Lexend (reading-ease optimised) for headings paired with
   Source Sans 3 for body — a pairing suited to healthcare
   and accessibility (patients reading about a diagnosis
   benefit from lower visual/reading strain).
