   PRINTING AN IN-APP PAGE

   Every screen in the app sits inside a 240px sidebar and a header bar, and

   and CLIPS whatever does not fit, so the right-hand end of every wide table
   came out of the printer cut off mid-word — the moderation Faults column and
   the J1 comments, but equally any other table in the app. The data was never
   missing; the layout lost it.

   This is deliberately in layout.css rather than in one feature's stylesheet:
   the shell is what causes it, so the shell is what fixes it, once, for every
   page. Standalone print templates do not extend this layout and are untouched.
