Glass buttonUIBarButtonItem on iOS 26stock · do not build
iOS 26 wraps every bar button in glass; the app sets only the tint. Circles hold a glyph, capsules a label. Content buttons are app-styled UIButtons, never glass.

Do not. Put glass on a content surface or stack glass on glass. Glass is the bar's, not the content's.
