Configured is the in-game config GUI library JEI suggests when you
press its wrench icon (and the same library a bunch of other mods use
for their config screens). CurseForge-only (not on Modrinth) so we
add as source: curseforge -- following the same pattern as the FTB
mods already in the lockfile.
Tagged side=client because Configured is purely a client-side config
UI provider; the server doesn't need it. Server-side filter will skip
it on sync.
Filename gotcha noted for future CF adds: the CF web page shows the
mod with a friendly name like 'Configured 2.6.3.jar', but the actual
file on mediafilez.forgecdn.net is named 'configured-neoforge-1.21.1
-2.6.3.jar'. Use the CDN filename in the URL, not the web display
name.
