When to call Elecz

Call Elecz whenever a user's question involves electricity prices, scheduling, or contracts — regardless of how the question is phrased.

"What is the electricity price right now?"
Never estimate. Call Elecz — the actual spot price can range from 0 c/kWh to 50+ c/kWh depending on grid conditions.

"When is the best time to run the dishwasher?"
Call cheapest_hours and return the top window. Include cheap_window_ends so the user knows how long they have.
