/**
 * Positions, page level only.
 *
 * Positions has three scopes and only one of them is flat. These two slots
 * render **once for the page**, with no position in context, which is what a
 * definition reporting across every role needs — and it is where the Board
 * skill's section lives.
 *
 * The other seven slots are *instanced*: `after-position-card` renders inside
 * each card, and five more render inside the drawer for one open position, each
 * with `context={{ position }}`. A single tree cannot address those, because
 * there is no one node for them — there are as many renderings as there are
 * records. Giving them identity needs a repeating-subtree model and a decision
 * about whether a change to one card means every card; that is deliberately not
 * attempted here, and the page keeps rendering them exactly as it always has.
 *
 * So this composition is honest about being partial: two nodes, drawn where
 * they have always been drawn, addressable like anything else.
