| // Zenmoji resizing image to multiple variants (maybe Apple Genmoji also does? didn't confirmed currently since I don't have a device installed iOS 18.2) | ||
| // but iOS 18.0 accepts even with one variant. | ||
| // also, in Mastodon, emoji (file) size is pretty limited | ||
| // so **i guess** we don't need to create small size | ||
