v1.3.18

Changes

• Fix: partlycloudy showing plain cloud instead of cloud-with-sun/moon — the cloud-coverage inline SVG rendered a tiny sun or moon that was nearly invisible at 25–35 px icon sizes. Coverage shading is now limited to the cloudy condition only. partlycloudy falls through to the CDN partlycloudy-day / partlycloudy-night icons, which clearly show the sun or moon and are already chosen correctly by the day/night calculation.
