/* ABM Roofing - exemplar concept site.
   Built 2026-11-03 as the standard for Paul's concept sites.

   The brief this demonstrates: a trade website is a sales tool, not a brochure. Every block
   below exists to move a worried homeowner one step closer to picking up the phone, and
   nothing on the page is invented - every claim traces to abm-roofing.co.uk. */
