Extra Special Lib (ESL)

shipped

ESL is the foundation library: registries, config helpers, Wave and Lobby session APIs, and other backend contracts Extra Special mods depend on. No GUI and no packets — session machinery lives here; networking is ESN.

Session/runtime half of ESL + ESN. Base of ESL → ESC → ESH / ESG / ESB.
