FQuartzUIAccessibilityPolicy

Internal type. Validation and pacing for browser-requested platform announcements.

Prerequisites / integration: Exact local player and configured app; Slate/UMG dependencies for native presentation work. Use the QuartzUIAccessibility recipe in the host module QuartzUIRuntime.

Minimal example / lifecycle: client.request('quartzui.accessibility.announce', {message:'Saved'}). Per-view rate/lifecycle gate; native handler stays private.

Avoid: Claiming full OS DOM screen-reader traversal. This named helper is runtime-owned; inspect/use it through the owner above rather than constructing it in gameplay.
