Problem

The animated card endpoint at app/routers_v2/players.py line ~863 returns media_type="image/png" for APNG files. While APNG is technically valid PNG, Discord and browser clients may not animate the content correctly when served as image/png.

Fix

Change media_type="image/png" to media_type="image/apng" on the animated card endpoint response.

Impact

Low effort, high correctness. T3/T4 animated cards may not display animations in some clients without the correct MIME type.
