FTUX Onboarding doesn't scroll, and I can't hit the finish button after setting up

[blakemcanally]

Bug

On the machine onboarding flow (step 4 — "Configure your default model settings"), the "Next" button is not visible and the page cannot be scrolled to reach it. This blocks completing first-time setup entirely.

Installed from: MSC (internal release)
Version: v0.4.22 (latest)
Platform: macOS (corp laptop)

Screenshot

Expected

The docked "Next" CTA at the bottom of the screen should always be visible, regardless of content height.

Analysis

The OnboardingFooter portals the CTA into a position: fixed; bottom: 5 slot rendered by OnboardingFooterProvider. The slot lives inside the MachineOnboardingFlow container which has max-h-dvh overflow-y-auto.

Hypothesis: on shorter displays (or default Tauri window size from MSC install), the fixed footer slot is either clipped by the overflow-y-auto ancestor or trapped by a CSS transform from OnboardingSlideTransition establishing a containing block.

Workaround

Resize the Buzz window taller, or Tab-focus to the hidden button and press Enter.

Fixed in #2496 — onboarding step frame scrolls under the docked CTA.
