   innomfg.com, "The Drawing Sheet"
   The whole site is laid out as an engineering drawing: zone markers around
   the frame, balloon callouts for sections, dimension lines, ruled spec
   tables, a revision block for notices and a title block for the footer.
   Ink blue on vellum, revision red for changes.
