Tune camera and timeline controls, add globe fly-to

- Clamp binder/timeline zoom ranges and disable OrbitControls zoom,
  using custom smooth zoom instead
- Disable middle/right mouse buttons; reduce rotate speed
- Fly camera to picked marker on globe click
- Rebuild leather surfaces with a regular grid for smooth curvature
- Refine suede and kraft paper textures, punch real page holes
- Reposition axis, time labels, and detail card; speed up iris fade
