Glassic Mist Blue Theme: Ultra-Light Mist Blue Overlay + Cloud-Fog Motion + Frosted Glass Texture

The DeepSeek Harness theme plugin `dsh-glassic-mist-theme` provides a misty blue overlay and frosted glass effects for web interfaces. It overlays a bottom-layer cloud and mist animation with a 74-second cycle and applies frosted glass styling to all components, using different blur levels across different layers. It supports density adjustment (10%–100%) and can be toggled via quick commands. Installation requires mounting the plugin in `node_modules` and registering its dependency, and it leaves no residual changes after being disabled. This solution optimizes performance and includes Safari-specific opacity adjustments.
