//! Last.fm fetchers — user listening statistics (recent scrobbles, top artists / tracks /
//! albums) plus global charts.
//!
//! Every request targets the fixed host `ws.audioscrobbler.com`. Config-provided fields
//! (`user`, `period`, …) only change which resource on that host is queried; the API key
//! never leaves to an attacker-controlled origin. Classified as `Safety::Safe`, same model
//! as the `github_*` family.
//!
//! Auth: `LASTFM_API_KEY` — create one at https://www.last.fm/api/account/create and put it
//! in `$HOME/.splashboard/secrets.toml`.
