+"""Duplicate a Shopify theme by copying every asset into a new unpublished theme.

+Usage:

+Creates an empty unpublished theme, then GET/PUT-copies each asset (text via
+`value`, binary via `attachment`) with 429 backoff. Live theme is never touched.
+Reversible: delete the new theme to undo. $0 (theme API is unmetered).
