/* ═══════════════════════════════════════════════════════════════
   Pediatric Fever Dosing Sheet — styles.css (monograph redesign)

   DESIGN SYSTEM — "pharmacopoeia monograph"
   The two drugs are distinguished by RULE STYLE, not just color,
   so the sheet remains fully legible on black-and-white printers:

     · Acetaminophen (Tylenol)  →  SOLID rules · FILLED markers
     · Ibuprofen (Advil)        →  DOUBLE rules · HOLLOW markers

   On screen, color reinforces the system (oxblood / amber on a
   clinical green-teal structural ink). In print, everything
   collapses to black ink on white paper with zero loss of meaning.

   All class names and IDs are unchanged — script.js untouched.
