Fix: zoomOptions prop override not working due to hardcoded values

The zoomOptions prop added in #41 isn't working as intended because values are being hardcoded in document.ts rather than being passed through to internal.ts where the defaults are handled.

Steps to reproduce:
1. Pass custom zoomOptions to Root component
2. Observe that minZoom remains at 50% regardless of prop value

Expected: Custom zoomOptions should override defaults
Actual: minZoom stuck at 50% due to hardcoding in document.ts
