/* ==========================================================================
   RecallDesk Clinical Design System
   Front-desk reception ergonomics for independent dental practices (1–4 operatories).
   Optimized for high-interruption desktop reception workflows:
   - Operatory-column schedule layout (1-4 hygiene chairs)
   - Generous line height (1.68) for all-day screen legibility
   - Humanist serif / clean sans typographic pairing
   - Soft clinical neutrals with accessible restorative teal accent (WCAG AAA)
   - Rounded calm component shapes and clear clinical status chips
