/* ────────────────────────────────────────────────────────────
   Medicine — Patient app prototype
   Design tokens. Warm, calm, clinical-but-humane.
   Aesthetic system declared up-front:
     · Type: Literata (display, serif, кириллица) +
             Manrope (body, humanist sans). Both Cyrillic-friendly.
     · Color: warm off-white background, sage primary, sand accent.
       Chroma stays low (≤ 0.05) — no saturated UI panic colors.
     · Density: generous. Audience is 40+. Base 17px, CTAs ≥ 20px.
     · No emoji in system voice. Curator voice is allowed warmth.
