Backend-themed sweep palette for the active-border glow, or null to use
the overlay's built-in palette. Only a list whose every entry parses is
accepted — a half-broken palette falls back wholesale rather than
silently swapping in partial colors.
Master data-capture gate (flags.dataCapture). An explicit false
short-circuits the whole capture pipeline, so it folds into both cache
gates below — mirroring the React SDK and the backend validator, which
rejects a stored config that claims a capture child is on while the
parent is off.
Whether the synthetic-gesture FALLBACK (flags.nativeBridge) may run —
the tap ladder's synthetic-pointer rung. Polarity is the usual one:
unknown ⇒ ON, only an explicit false disables it.
Whether live UI trees may be SENT while the widget (FAB) is hidden — e.g.
during the per-screen button delay, or on a hidden-by-default screen of a
call kept alive there. Defaults true (Android parity,
treePush.transmitOnHiddenWidget, owner decision 2026-08-27): a call
starts only where the widget shows, so this matters only for a call that
is still running. Host screen exclusions (disabledRoutes) still apply
independently of this flag — nothing looks past those.
