Overview

---- root ------------------------------------------------------------------- Solid's createRoot: an ownership scope that is not an effect. Effects and cleanups created inside the block belong to the root and live until #dispose — the lifecycle anchor for long-lived graphs (a session, a connection) whose teardown is an external event, not a rerun.

Deliberately detached: a root created inside a running effect is NOT adopted, so the enclosing effect's rerun/disposal leaves it alone (Solid's escape hatch from the owner tree). Whoever holds the root disposes it.

The block runs untracked (Solid clears the Listener in createRoot): a root built mid-effect must not subscribe that effect to signals it reads.
