 * Lightweight validation-only module.
 * Import from here when you only need to validate codes, not look up data.
 * Bundle size: ~50KB vs ~4MB for full library.

 * @example
 * ```ts
 * import { airport, airline } from "aviation-codes/validate";
 *
 * airport.is("LAX");  // true
 * airline.is("AA");   // true
 * ```

 * @module
