Backend PR: https://github.com/snag-tcg/tcg-collector-backend/pull/651

Restore the supplied P-fruit artwork for the Promo block, matching OP, X and ST. The horizontal Promo logo remains assigned to the child series. Both original PNGs and their SHA-256 hashes are preserved in the backend repository for later bronze-to-gold promotion. The app uses its existing semantic mask tint.

The block-logo regression failed on the old association. After correction, 1677 API tests passed, 42 skipped, zero failures; TypeScript compilation passed. Production and on-device checks remain pending. Publish the two new hashed image files before deploying the API. No migration or mobile build is required for clients already consuming backend block_logo metadata.
