TITLE: Nimbus — Weather for Port Aurelia FILE: 012-nimbus-weather.html === PROMPT (exact prompt used) === Build "Nimbus", an elegant weather dashboard for the fictional coastal city of Port Aurelia (clearly fictional sample data). The hero is an animated sky that changes with the selected condition: clear day (drifting sun glare, soft clouds), rain (parallax raindrops, darker gradient), snow (flakes with sway), thunderstorm (lightning flashes) and clear night (stars, moon). The palette adapts per condition but stays sophisticated (e.g. day #7cc4f5 → #e8f6ff, night #0b1026 → #2b2f63). Foreground glass cards: current temperature as a huge thin numeral, feels-like, humidity and UV; an animated wind compass; a sunrise/sunset arc with the sun's current position; a 24-hour temperature line chart (SVG smooth curve with gradient fill and hover tooltip); and a 7-day forecast strip with custom SVG weather icons that animate on hover. Interaction: clicking a forecast day switches the whole scene and its data with a smooth cross-fade; a °C/°F toggle. Typography: a clean sans with tabular numerals. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
