   StoneBase Paving & Landscaping — stylesheet
   Art direction: calm, gallery-clean surfaces (Apple-inspired restraint) with
   the StoneBase brand kept intact — disciplined crimson accent, charcoal ink,
   a whisper of warm stone. Type: Archivo (display) / Hanken Grotesk (body).
   Generous whitespace, hairline structure, soft light, quiet motion.
