# Animated Navigation Dropdown Clipping Fix

Resolves a layout stacking error where expanding mobile navigation slide windows drop underneath subsequent block layers.

## Resolution
- Enforced an explicit stacking layer priority threshold (`z-index: 1000`) on the navigation container parent wrapper.
- Isolated container layers to ensure drop components overlap surrounding document fragments predictably.
