NAP data is consistent across the site

NAP inconsistency — variations in your business name, address, or phone number across footer, contact page, JSON-LD schema, and config files — is one of the most heavily weighted negative factors in local search ranking algorithms. Citation aggregators and Google's local index cross-reference every mention of your NAP data; even minor format differences like Main St vs Main Street or (555) 555-1234 vs +15555551234 create conflicting signals that suppress local pack placement. This is a schema-org LocalBusiness correctness issue with direct revenue impact for any location-dependent business.

Centralize all NAP data in a single source-of-truth module and import it everywhere it's rendered or serialized.

// src/lib/business-info.ts
export const BUSINESS = {
  name: "Springfield Plumbing",
  phone: "+15555555555",
  phoneDisplay: "(555) 555-5555",
  address: {
    street: "123 Main Street",
    city: "Springfield",
    state: "OH",
    zip: "45501",
    country: "US",
  },
} as const;

Replace every hardcoded NAP string in src/components/footer.tsx, app/contact/page.tsx, and any JSON-LD generator with imports from this file.
