// Wilshire Blvd Corridor ingest — every registered business on the ~16-mile
// stretch of Wilshire Boulevard from Downtown LA to the Pacific Ocean.
//
// Wilshire Blvd is essentially LA's "main street" — 16 miles of nearly flat,
// straight east-west corridor from Wilshire/Grand (DTLA) west through:
//   - MacArthur Park / Westlake (City of Los Angeles)
//   - Koreatown
//   - Mid-Wilshire / Hancock Park
//   - Miracle Mile (LACMA, Petersen Automotive Museum)
//   - Beverly Hills (Wilshire crosses through 90211/90212/90210)
//   - Westwood (UCLA, Federal Building)
//   - Brentwood
//   - Santa Monica → ocean
//
// "Registered with the city" = LA Office of Finance BTRC for City-of-LA
// stretches, plus Beverly Hills + Santa Monica business licenses for those
// jurisdictions. Same approximation pattern as Sunset/Ventura: pull every
// commercial OSM presence on/near Wilshire Blvd, tag them
// `corridor: 'wilshire-blvd-16mi'` for filtering.
//
//   node scripts/ingest-wilshire-corridor.js          # full corridor ingest
