//! Settings (After Effects' Preferences): a versioned serde model, addressed by dotted keys
//! (`general.undoLevels`, `autoSave.intervalMinutes`, `labels.3.name`), plus the page schema the
//! Settings dialog and agents (`prefs.pages`) are built from.
//!
//! Settings are stored as JSON (`prefs.json`) through the session's [`crate::config::ConfigStore`].
//! Loading is forgiving: missing keys take their defaults, unknown keys (written by a newer
//! version) are kept and written back, and older layouts are migrated ([`migrate`]).
//!
//! Every setting in [`pages`] says whether it already changes behaviour (`live`). Settings that
//! don't yet are still shown (After Effects parity of the dialog) and are listed in
//! `docs/preferences.md`; a test keeps that list in step with the schema.
