/* StruXure.co v3 tokens, base and components, on the Kinetech family system (6 Nov 2026).
   Family source: kinetech-scheme-lab-20261028/site/home/opt-1-the-map/style.css :root and base rules, the set the
   Kinetech home, manufacturing and PSN pages share (Jost 600 headings in #102d7b, Montserrat body 16/1.65,
   teal-deep buttons and links, mist and slate grounds, white cards with the family shadow, 96px sections, 1180 wrap).
   StruXure keeps its own: the plan-sheet drawings and title blocks, stamps, the drafting grid on navy bands,
   and #00A1E0 as the drafting line and accent.
   Load order on a page: sx-tokens.css, sx-draw.css, sx-chrome.css, then the page's own css.
   Fonts: Jost 500/600/700 and Montserrat 400/500/600/700 from Google Fonts (see _shared/README.md). */
