/**
 * `Session` — a user-named workspace that owns one engine snapshot.
 *
 * Sessions partition the demo app: each one holds its own documents,
 * annotations, evidence items, and links. Membership is implicit — a
 * session "owns" whatever lives in its engine snapshot. The session
 * record itself only carries the human metadata (name, timestamps) and
 * the branded id used as a key in `localStorage` and the ZIP archive
 * (see ADR-0008).
 *
 * The id is opaque (`sess_<uuid>` per `ids.ts`). The name is the human
 * label; uniqueness is enforced by the `SessionService` on create and
 * rename. Names are *trimmed* before storage so a leading/trailing
 * space does not let two sessions coexist with effectively the same
 * label.
