// sources/la-county.js — canonical Los Angeles County place set, used as the geographic in-band gate.
//
// WHY: the tracker started SFV-only with a hand-kept neighborhood allowlist. Scope is now "all LA
// County" — so instead of appending cities one batch at a time, this is the authoritative set every
// captured listing's city is checked against. Covers (1) all 88 incorporated cities, (2) the major
// City-of-Los-Angeles neighborhoods that appear as "city" in listing feeds, and (3) the common
// unincorporated communities (Altadena, Marina del Rey, Topanga, East LA, etc.). Names are stored
// lowercased; match with LA_COUNTY.has(city.trim().toLowerCase()).
//
// Maintenance: if a real in-county listing is dropped because its feed used a name not here, add the
// alias — don't loosen to a substring match (that would pull Orange/Ventura/SB county bleed).

// (1) The 88 incorporated cities of Los Angeles County.
