"""Config flow for TaskMate integration.

Only the initial setup flow lives here. Day-to-day configuration (children,
chores, rewards, task groups, settings, notifications, badges, templates, …)
is handled entirely by the dedicated TaskMate admin panel at
``/taskmate-admin``. The legacy options/configure flow was removed in v4.0 —
all of its functionality is available in the panel, and all data is stored in
the integration's own ``Store`` rather than in ``config_entry.options``.
