Deletes the preview's live-controls strip — mic meter + speaker + volume, the game-audio chip,
the TRAX button and the lip-sync slider — and the three code-behind handlers that served it.
One sound surface instead of two: the same gains in two places was the original duplication, and
two places to set a gain is how a creator ends up with a meter that disagrees with what they hear.
~16.7 KB of XAML and 60 lines of event code gone.
Verified: the preview still loads and its interactions still work (selected-layer hit testing, the
socials preview, the brand-logo preview), plus the theme's resource guard.
