"""Pipeline layout: bin nodes by ``stage``, place left-to-right.

Phase 1 ships an empty stub — the legacy ``computeRankedLayout`` JS
function (inside the story view's IIFE) continues to provide the L→R
"Flow" layout, which now uses the real ``topological_rank`` stamped in
Phase 1a.

Phase 1d adds a true Story-view layout here that bins by
``preprocessor.stage`` rather than rank, sorts each stage column by
``(visual_rank, importance)``, and computes anchor points for the edge
bundles emitted by ``preprocessor.bundles``. See the plan section
"Phase 1d".
