Glass Dark UI Skill

Use When

• A dark interface needs frosted glass panels, blur shells, or gradient/glow borders.
• You need the implementation — tokens, backdrop-filter recipe, masked gradient border, contrast floors — for a dark glass surface.

Choosing between the dark skills: use this one for the concrete CSS of a glass surface. Use visual-style-presets (dark-glass-workspace preset) when you need the whole page direction — layout shell, structural motif, accent discipline. Use visual-style-presets (dark-technical-framed) instead when the identity should come from frames and rails rather than blur, and mesh-gradient-dark-blue-clean when the background itself is an animated mesh field.
