   PRINT — Clinical reference output
   ──────────────────────────────────────────────────
   Doctors and pharmacists frequently print individual drug pages for
   ward rounds, hand-over notes, or to leave bedside.  This stylesheet
   strips the chrome (sticky bars, palette, FAB, compare overlay) and
   forces a print-friendly layout so all section content is visible
   without horizontal-scroll truncation, links print without colour
   noise, and pages break cleanly between section cards.
