/* 
  Design: Inspired by the sandstone quarries and forest landscapes 
  of northern Saarland. Earthy, grounded palette with sharp geometry 
  referencing paving stonework — the company's core trade.

  Typography: "Crimson Pro" for editorial warmth in headings,
  "DM Sans" for clean body text. Both embedded locally would be ideal,
  but since no CDN and no local fonts provided, we use a curated 
  system stack with personality.
