Non-negotiable rules

Do not use iframe code or markdown links for podcast embeds in Substack.
Prefer duplicating the existing Substack draft template that already has a working embed block.
If creating a fresh post, use /embed and confirm the player card renders before publishing.
Use top-level Apple Podcasts show URL for reliable fallback.
