  "unit": "per opening, typical US residential replacement window",
  "scope": "Continental US, mid-grade vinyl / fiberglass / equal unless noted. Impact glass, oversized, wood-clad, and historic sash sit above these bands.",
  "disclaimer": "Ranges are typical 2026 US trade quotes plus dated public anecdotes. They are not a national survey, not a bid, and not a Buildtana Smart Offer. Firm pricing is always project-specific.",
  "methodology": "Three channels are scored separately so a financed installed quote is never compared to a supply-only SKU. Sales-company = in-home replacement franchise / pitched installed package. Dealer = millwork or lumberyard product plus independent or dealer labor. Supply-only = product EXW or DDP; labor hired locally. Observations are labeled anecdotal when they come from public quotes rather than a bid book.",
