Fix VR config panel positioning to prevent overflow below handle
The VR config panel was extending 55cm below the handle bar due to incorrect positioning calculation. Problem: - Panel dimensions: 2m wide × 1.5m tall - Panel was positioned at y=0.2m above handle center - This placed panel bottom at y=-0.55m (55cm BELOW handle) - Panel overflowed significantly below the handle bar Solution: - Calculate proper position based on panel height - Position panel center at y=0.8m (0.75m half-height + 0.05m gap) - Panel bottom now sits 5cm above handle, matching toolbox appearance - Add 0.6x scaling to match toolbox compact size (1.2m×0.9m actual) Result: - Panel bottom aligns just above handle bar - Consistent visual relationship with toolbox - Comfortable viewing distance and ergonomics in VR 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
