/**
 * Optional RTS binding composition over the genre-agnostic selection-bookmark
 * store (`@jgengine/core/scene/selectionBookmarks`). It maps the classic control-
 * group idiom — Ctrl+digit binds, digit recalls, a second digit tap within a
 * window focuses — onto opaque bookmark keys, without pulling input mapping into
 * the store. Games that want a different scheme (named bookmarks, gamepad, touch)
 * skip this and call the store directly.
 *
 * The resolver is pure: it turns a decoded key event plus the last-recall memory
 * into an intent, so the same logic works under any capture layer and stays
 * replay-safe. The caller owns actually binding/recalling and the focus hook.
