# OpenUSD Composition

Manage layer composition arcs: add sublayers to the root layer, attach
payload arcs on prims, create variant sets, and set variant selections.
Reference arcs remain in `openusd-stage`. Requires the pxr OpenUSD runtime.

## Workflow

1. Ensure a stage exists.
2. `add_sublayer` — compose another layer under the root layer.
3. `add_payload` — attach a payload arc on a prim.
4. `add_variant_set` — create a named variant set on a prim.
5. `set_variant_selection` — switch the active variant in a variant set.
