v0.27.0

Changed

• In the Simulate panel, an entity attribute that has a known set of values
  (such as a remote's current activity) is now editable via a dropdown of those
  values — matching the scene editor — instead of a free-text field.

Fixed

• The state value dropdown (in the scene editor and the simulator) now offers
  both On and Off for remote, automation, script, siren, humidifier, update and
  calendar entities, instead of only the entity's current state.
• On phones the Simulate panel no longer squashes the entity name into a narrow
  column or scrolls sideways — each row's controls now wrap onto their own line.
• Deleting the Ambience integration now also removes its stored data (scenes,
  scopes, switch and condition settings). Previously this data was kept on disk,
  so removing and re-adding the integration silently restored all your old
  settings instead of starting fresh. A reload or Home Assistant restart still
  preserves your data as before — only an explicit delete clears it.
• When configuring an action's fields, each field's checkbox now lines up with
  the field name at the top of the row instead of floating in the vertical
  centre of multi-line descriptions.
