com.blueyvatar.image

One image. By default an avatar; see purpose for gallery images. The blob holds the full original (long edge up to 4096 pixels). The optional crop says which square of it to show; without one, delivery takes the center square. The blob size limit matches the reference PDS default, so an image above the app.bsky.actor.profile#avatar limit of 1,000,000 bytes cannot be reused there as is.
