//! `serve-tiles` subcommand — local HTTP server for `PMTiles`
//!
//! Serves vector tiles from a local .pmtiles file via HTTP.
//! Default endpoint: <http://localhost:8080/{z}/{x}/{y}.pbf>
//!
//! NOTE: Requires `axum`, `pmtiles`, and `tower-http` crates to be vendored.
//! Until then, this command returns an error indicating missing dependencies.
