Title: Weather Cathedral Prompt: A reverent forecast hall where each city is a chapel and weather moves like procession. Combine an arched canvas viewport, hourly chapels, and a seven-day aisle. It should feel solemn and luminous — gold tracery and storm glass on midnight slate. Design: A split nave joins an arched forecast frame with live snow, rain, sun, and storm canvas to a sermon intro with mode buttons and verses; below, three aisles hold city chapels, hourly and seven-day readings, and a vestry with alerts and log. Arched frames and dashed verse cards carry the cathedral language. Visual techniques: - Canvas weather engine with four modes and lightning flashes - Arched forecast frame with gold tracery border - Hourly chapel tiles and seven-day procession bars - Candle-flicker and rise-in keyframes - Gold-ice-storm on midnight slate palette Interaction model: Users pick cities or weather modes, switch units, click hours for readings, arm storm alerts, draw new verses, and log every reading while the canvas and arch update to the chosen sky.
