   Honeystone Landscaping — homepage mockup
   Concept: the page is built like a dry stone wall. Photographs are laid in
   level courses with staggered joints, dark sections are capped with coping
   stones, and one diagram explains how a wall actually stands up.
   Type: Vollkorn (text and headings) + Forum (cut-letter capitals).
