--bmc-color duplicates the value of --theme-orange in this theme. To avoid drift if --theme-orange is updated later, set --bmc-color to reference the theme variable (e.g., via var(--theme-orange)) instead of repeating the hex value.

Suggested change

	--bmc-color: #cb4b16;
	--bmc-color: var(--theme-orange);

This workflow grants contents: write and pull-requests: write to a reusable workflow sourced from another repository (and referenced via a floating @main ref). With secrets: inherit, this materially increases supply-chain blast radius if the upstream workflow changes. Consider pinning the reusable workflow to an immutable ref (tag/SHA) and scoping token permissions (and passed secrets) to the minimum actually required for the release job.
