/* ============================================================
   MATT OS 98 — shared program chrome (.prg)
   One canonical copy of the program-window frame used by every
   in-fiction "program" screen: WORK.EXE, ARTICLE.EXE, MATT.EXE,
   the disk directories, file readers, and the fatal-error screen.
   Loaded site-wide except the front page (which is self-contained).
   Templates may override any of this in their own <style> blocks —
   inline template CSS comes later in the document and wins ties.
