+/// Shows a themed, transient confirmation toast plus a light haptic tick.
+///
+/// Rendered as a fixed [SnackBar], so it settles just above the app's bottom
+/// chrome (mini-player + tab bar) rather than over it. Styled to match the
+/// dense, near-black terminal aesthetic — [TimbreColors.surface] fill, warm
+/// [TimbreColors.foreground] text, with the live accent used for the leading
+/// [icon]. Any in-flight toast is cleared first so rapid taps don't stack.
