Yip, it uses ligatures, but it also has a system where you can say put a box around text by using the underscore character w/ square braces ("[_mi_pilin]" has the "mi" and "pilin" characters with a cartouche around them, like on the second line of the linked page below), and also I think does dynamic compounding of characters (see the current complete character list here - https://davidar.github.io/linja-pona/nimi https://davidar.github.io/linja-pona/nimi - I haven’t asked the author how they did it, but my guess is that there’s something fun/dynamic going on).
