/* Express Commercial Roofing & Contractors — Design DNA
   Mood: Commercial-industrial precision — a blueprint and skyline, not a
   residential shingle-and-ladder shop. Steel, not shingle-brown.
   Color: cool graphite-slate canvas, steel-blue brand + safety-orange
   accent (Committed cool-lane palette — distinct hue and dominant-neutral
   role from every warm/earthy build in this pool)
   Type: Barlow Condensed (display, industrial condensed) + Source Sans 3
   (body, workhorse sans)
   Layout: skyline silhouette hero band, spec-sheet service list (not a
   card grid), diagonal-cut CTA band
   Motion: calm, slow draw-in — quint easing
   Signature element: animated architectural skyline/roofline silhouette
   line-draw across the hero, with a single safety-orange measurement tick
