   Dean Plumbing & Repair — client brand system
   Derived (not sourced) per client-demo-site §1's fallback clause: no
   review text, no business photos, no existing website to extract from.
   Seeded by: the trade itself (pipe, fittings, brass, gauges), the hero
   photo's own tones (navy workwear, cool tool-handle blue, white fixture,
   dark worktop, a small red fabric tag), and the one genuinely repeated
   real fact — 30+ years in service (MapQuest). See README for full sourcing.
