Liquid Glass — the material

Composed 2026-08 and verified against developer.apple.com and SDK interfaces. Every rule carries an availability floor and a confidence tag: [verified] (checked against Apple docs/SDK this composition), [apple] (Apple doc, unverified), [multi] (corroborated by multiple independent accounts), [single] (one account — verify before relying), [version-pinned] (bug workaround tied to OS versions; recheck on updates).
