"""Single source of truth for global-setting validation.
Each writable global setting is declared ONCE here as a ``SettingSpec`` (key +
type + optional numeric range / string cap). The WS write handler
(``websocket/dashboard.py``) derives its allow-list and range/cap tables from
this registry, and the options flow (``config_flow_options_global.py``) pulls
its NumberSelector min/max from the same specs — so the ranges can't drift
between the two surfaces (they previously lived as three hand-kept copies).
Bespoke normalisation that isn't a plain range/cap (panel-title trim,
title-style enum, quiet-hours regex, list sanitisers, notify-service
validation) stays in the WS handler; the registry only covers the mechanical
type + range + length checks.
