+# Global Layers
+
+Create components that persist across slides.
+
+## Layer Files
+
+Create in project root:
+- `global-top.vue` - Above all slides (single instance)
+- `global-bottom.vue` - Below all slides (single instance)
+- `slide-top.vue` - Above each slide (per-slide instance)
+- `slide-bottom.vue` - Below each slide (per-slide instance)
+- `custom-nav-controls.vue` - Custom navigation controls
+
+## Z-Order (top to bottom)
+
+1. NavControls / custom-nav-controls.vue
+2. global-top.vue
+3. slide-top.vue
+4. Slide Content
+5. slide-bottom.vue
+6. global-bottom.vue
+
+## Example: Footer
+
+```html
+<!-- global-bottom.vue -->
+<template>
+  <footer class="absolute bottom-0 left-0 right-0 p-2">Your Name</footer>
+</template>
+```
+
+## Conditional Rendering
+
+```html
+<!-- Hide on cover layout -->
+<template>
+  <footer v-if="$nav.currentLayout !== 'cover'" class="absolute bottom-0 p-2">
+    {{ $nav.currentPage }} / {{ $nav.total }}
+  </footer>
+</template>
+```
+
+## Export Note
+
+Use `--per-slide` export option when global layers depend on navigation state.
