FlatLaf is loaded at runtime through slimjar like the other libraries.
Every studio window now opens with FlatLaf's dark look tuned to the
IntelliJ New UI colours, and shares a small kit of controls: a flat
toolbar, toolbar buttons and tabs, search boxes, a status bar and the
rounded cards drawn over maps.

Paper still provides Adventure at runtime. Every Adventure method Iris calls has the same signature in 4.17 and 5.2.0, so older servers keep working.

Core now compiles against paper-api instead of spigot-api. PaperLib is
replaced by Paper's native async chunk and teleport API, and the Spigot
fallbacks (Medieval pregen method, sync chunk loading) are removed.
Adventure is no longer bundled and relocated: Paper ships it and every
CommandSender is an Audience, so the BukkitAudiences wrapper and ShadeFix
go away.
Iris now refuses to enable on servers without the Paper API, with a clear
message instead of failing later at runtime.
