"""Single source of truth for task-field enums + numeric ranges.

The task/trigger forms exist in TWO hand-written UIs (the panel's
``task-dialog.ts`` and the HA options config-flow) plus the WS create/update
schemas and the sanitizer. This module pins the *values* those surfaces must
agree on — enum option sets and numeric bounds — so they are consumed from one
place on the Python side (WS schemas, sanitizer, config-flow selectors) and
enforced against the TypeScript dialog by the parity tripwires in
``tests/test_frontend_const_parity.py`` / ``tests/test_parity_task_fields.py``.

This is the field-level companion of ``helpers/settings_registry`` (which does
the same for the global settings). Full form *generation* from these specs is
the remaining long-term step; until then, a new enum value or bound changed
here propagates to every Python surface by construction and fails the build if
the TS dialog wasn't updated.
