# Experimental-platform notice - the RENDERING half. The decision lives in
# UI/Classes/ExperimentalPlatformNotice.ps1 (loads under both backends, so the gate
# is unit-testable on Windows); this file only draws it.
#
# Avalonia only, by design: the notice never shows on Windows, and WPF is the only
# backend there - so there is no WPF twin to keep in sync.
#
# Closure law: click handlers run through ConvertTo-AvaloniaEventScriptBlock, which
# strips function-local captures but keeps module scope. The handler below therefore
# reads the checkbox off $S.Tag and calls module functions by name only - never a
# local, never $script:UIProvider.X(). See UI/Avalonia/CLAUDE.md.
