/* ---------- Main pane state machine ---------------------------------------
 * The main pane carries `data-main-state="empty|loading|graph|error"`.
 * Each child surface is tagged with one or more `graph-state-<name>` classes
 * indicating which states it should appear in. Anything not matching the
 * current state is forced to display:none, regardless of its `hidden`
 * attribute, so the states are *mutually exclusive* in the layout.
 *
 * Why a state attribute (not per-element `hidden`)? Earlier code juggled
 * `hidden` on each block independently and drifted — nodes rendered on top
 * of the empty hero. One attribute, one source of truth.
 *
 * `display: none` overrides the per-element class display rules. We then
 * use specific `display: <value>` for each element in its active state so
 * the layout (flex / block) is preserved.
