/* ==========================================================================
   ENGINEERING DRAWING — Build with it (Design Completion Campaign, 2026-09-29).
   The board is a drawing sheet: the room's white ground, a wide frame with a
   wider filing margin on the left, grid references on the top border, and
   each field a part keyed by an encircled numeral in that margin. Faces are
   the room's own (PlexSansX, PlexMonoX, declared in x-engineering-drawing.css).
   Widths from the grammar's 4:2:1 series only. Every class is ged- or scoped
   to .gm--engineering-drawing.
