/* ============================================================================================
   fabrica.css — the only stylesheet. No build step, no framework, no CDN request.
   Structure follows the sister project (tokens, mobile-first, 44px targets, card-collapsing
   tables), with three things deliberately done differently from day one:
     1. every table sits in a .table-scroll wrapper (overflow-x)
     2. the card break runs up to 60rem instead of 40rem — no untested tablet no-man's-land
     3. @media print exists from the start, because quotes and material lists go on paper
