/* ParaPrep, Medication (Monograph) Builder (Brief 20) page styles.
   Reuses the design tokens + base components from styles.css; adds the drug
   picker grid, the monograph skeleton (field slots) and the fact-tile bank.
   Shared chrome (footer-rich, demo-bar, draft badge) is duplicated per page by
   project convention (see algorithm-builder.css). Responsive 360 to 1280px. */
