Package reference

Every engine-generic capability is a subpath of the single @s2script/sdk package; CS2 game types are the separate @s2script/cs2. Prefer the root @s2script/sdk barrel for authoring. Import the types at author time — the engine injects the runtime at load. Every module page below is generated from the shipped type definitions, so its exports and signatures stay in lockstep with what you actually import.

Game-specific facts stay in @s2script/cs2 (and future @s2script/<game>). Litmus test: would this still be true on another Source 2 game? If no → game package.
