Expo Router is a file-based router for React Native and web applications.

/**
 * Merges composition component options into navigation descriptors.
 *
 * Expects the projected state where preloaded routes are appended after `index`.
 *
 * For each descriptor:
 * 1. If no composition options registered → pass through unchanged
 * 2. If route is preloaded (positioned after the focused route) → skip composition (pass through)
 * 3. Otherwise → merge descriptor.options with composition options (composition wins)
