/* ==================================================================
   Mechanic Do — "Drafting Table"
   The page is one engineering drawing: drafting-paper ground, a
   hairline construction grid, ruler rails with zone letters,
   cutting-plane section markers, blueprint detail plates, redline
   balloons and a title block footer.
   Plain CSS, no build step. All paths relative (served from a subpath).
