<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Low Risk**
> Test-only Maestro YAML changes with no production code impact.
> 
> **Overview**
> Updates **Maestro** onboarding and fire-button flows so dismiss taps
and visibility checks work with the new onboarding brand design.
> 
> Dismiss controls now target
**`daxDialogDismissButton|brandDesignDismissButton`** on the initial
dialog and
**`daxDialogDismissButton|contextualBrandDesignDismissButton`** on later
contextual dialogs, so tests pass whether the old or new dismiss control
is shown.
> 
> The “creepy ad loses its wings” copy assertion uses a looser regex
(**`its.wings`**) to match possible spacing or line-break changes in the
updated UI.
