TEST-ONLY: invoke applyProposedStyling directly on a detached, already-
painted svg node (as returned by __parseSvgForTest + __renderActiveLayersOnNode),
without requiring a live grid (toothSvgRoot/applyStateToSvg needs
registered DOM roots — see addTile()). Reads the module's live
charts/chartMode/planInitialized, exactly as the real
applyStateToSvg roots loop does. Not part of the public API.
