The walkthrough rode the default 50° orbit camera, which feels cramped on foot. Both walkthrough controllers (baked GlbWalkthroughController and the parametric WalkthroughControls fallback) now set a shared WALKTHROUGH_FOV = 60 on enter and restore the prior FOV on exit, leaving orbit framing untouched.
