Rework 3D view navigation: - Turntable / lock-horizon orbit: horizontal drag yaws about world +Z, vertical drag pitches about the horizontal camera-right axis, so the view never banks. Pitch is pole-clamped but the straight-down default view can still be tilted out of. - Orbit centre: the selection's centre when something is selected, otherwise the point under the cursor — no longer only the file centre. The camera revolves rigidly about the pivot, so it stays put on screen and the view doesn't jump. - Mouse scheme: Zoom = wheel, Pan = MMB, Rotate = Shift+MMB. Right-drag no longer orbits (right-click stays context menu / Enter). Floating viewports orbit with Shift+MMB too. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
