  name: Block heat (rolling 24h + temp guard + low-price bypass)
  description: >
    Blocks heating during the most expensive hours based on Nordpool prices.
    Works with both 60- and 15-minute prices and handles DST automatically.
    During cheap hours it mirrors the outdoor temperature at a configurable
    refresh interval, within min/max temperature guards and with a minimum
    change threshold to reduce unnecessary writes.
    Ignores placeholder prices (e.g. -0.001).
    Includes bypasses: never block when current price is very low,
