"""Pixiv — one quirk.

post_url: the sidecar's `url` (legacy gallery-dl era) is the image URL
on `i.pximg.net`, and the native post record (#129) writes no url key
at all — the permalink is synthesized from `id` here either way:
/artworks/<id>. external_post_id (= `id`) was already correct, so no
override there.

Downloads run through the native ingester (pixiv_ingester.py), not
gallery-dl; this registry entry still owns URL validation, sidecar
parsing, and the credential surface (the OAuth refresh token).
