Current Behavior or Documentation Gaps

Hi FastHTML devs,

glad to see a similar project to Ludic. The documentation mentions "we’ll list here other projects that have a similar approach to FastHTML", so I thought https://getludic.dev/ has very similar approach and could be mentioned there as well.

Side note: I also want to add comparison of Ludic to FastHTML, see getludic/ludic#86
