def material_semantic : Symbol | Nil #

Phase 5 v2 — Apple semantic material override. nil = HIG-canonical default :system_resolved (SwiftUI .alert is system-drawn; Apple explicitly recommends letting the system handle alert chrome). Setting this has no visible effect on the active SwiftUI .alert path; preserved for cross-platform symmetry with the other Category B widgets' material override surface.
