   ORT BÂTIMENT — DESIGN SYSTEM v2
   -------------------------------------------------------------------------
   Direction: premium construction & solar EPC. The visual signature is
   drawn from the company's own world — technical drawings, spec sheets
   and site surveys — rather than decoration for its own sake:

     • A thin vertical rule runs down every section like a drawing
       baseline, with a small monospace margin tag ("§02 — À PROPOS")
       marking each section the way a blueprint annotates a detail.
     • Photography is desaturated at rest and resolves to full colour on
       hover/reveal — the real jobsite work is the content, not a backdrop.
     • Space Grotesk (display) + Inter (body) + IBM Plex Mono (labels/data)
       — a technical, engineered pairing instead of a decorative one.

   Contents:
