/**
 * The link every tool holds: whichever of the two Aseprites this session is
 * working with, switched only by an explicit `preflight mode=…`.
 *
 * Both links are created on first use and kept for the life of the server, so
 * switching never loses anything: the user's window keeps its documents, and
 * the headless process keeps its own unsaved ones for when the session comes
 * back to it. Nothing here switches on its own — a live call that fails still
 * fails (docs/adr/0008-headless-mode.md).
