Swiftui Liquid Glass

This brings the iOS 26 Liquid Glass API into Claude's context with the full modifier chain, morphing transitions, and container rules. You get the glassEffect modifier, Glass struct with tint and interactive variants, GlassEffectContainer for blending, and the glassEffectID system for morphing animations. The workflow separates new feature work from retrofitting existing UIs, and the common mistakes section catches the usual gotchas like nesting containers or applying glass before layout modifiers. Useful when you're adopting the new design language and need the API details without hunting through Apple's docs, especially for the spacing and union mechanics that aren't obvious from method signatures alone.
