- so far they seem to exclusively use legacy color codes

- the random style has a special impl for periods, they turn into animated

colons that warp up and down rapidly

- motd_2 is ignored? client displays "motd_1 - v{version}", where the
|

appended version text is considered part of motd_1 for color code processing

- motd_2 seems to mainly be used to return the server software in use (e.g. PocketMine-MP)`);
