//! Module registry for the theme manifest's `[bar.slots]` (plan Phase 3a),
//! extended in Phase 3b to also route `widget:<key>` entries.
//!
//! Each bar module (`workspaces`, `media`, `clock`, `volume`, `wifi`,
//! `battery`, `control`, …) is still built exactly where it always was in
//! `main.rs` — this registry only decouples the ORDER in which those
//! already-constructed widgets get appended into the left/centre/right
//! containers from the fixed source-code order they were built in. main.rs
//! registers each widget by its manifest module name once construction is
//! done, then walks `ShellTheme::slots()` to append them in the theme's
//! order instead of a hardcoded sequence.
//!
//! A slot entry may also be `widget:<key>`, where `<key>` is either a
//! `WidgetPlacement` alias (`right_of_workspaces`, `left_of_clock`,
//! `right_of_clock`, `left_of_stats`, `tray`) or a Lua module name (see
//! `bread_shared::widget::WidgetSpec::module`) — these route through
//! `for_each_in_slot`'s `on_widget` callback rather than this registry,
//! since their containers are Lua-widget slots created on demand by the
//! caller, not modules registered here. `WidgetPlacement` itself is a wire
//! type from `bread-shared` and is never referenced in this file.
