/* StowLM Planner shell (PLANNER.md, contract v5; design in experiments/mvp/video/studio-demo/DESIGN.md).
 * A 2D stowage-planning tool: header with the stepper, load list, bay plan, step panel, status meters. White theme,
 * one harbour-blue accent, POD colours (Okabe–Ito), semantic pass/warn/fail always paired with words.
 * Modules use these tokens and classes; the v1–v4 st-* names are aliased at the end so reused module logic renders. */
