// Relief Semántico panel (extracted from Sidebar.js in H4 4.2).
// Owns the entire `#relief-submode-controls` block: comparison modes A/B/C,
// active-document list, scale/render/thickness controls, PDF selector + ingestion
// + search, and the Mode-C dimension inspector. The SAE and Model sub-panels are
// nested here and composed from their own modules to keep the DOM identical.
//
// Cross-panel: publishes ctx.refresh.{reliefFiles,docList,dimList,comparisonModeUI,
// subModeUI}; reads ctx.refresh.modelPanel. Also mirrors renderDocList/renderDimList
// onto window.* for visualizer/DimensionInspector.js.
