/* Ore Traceability (V1.44, Client\Apps\Traceability): the circuit's diagram (CircuitDiagram.razor), a pile's figures, layers
   and shares (PilePage.razor, TraceShares.razor), the accountability's chart and table (AccountChart.razor,
   AccountabilityPage.razor) and the settings' editor (SettingsPage.razor). Only the theme's tokens (app.css :root and its
   dark values): light and dark alike. Linked by Components\App.razor after app.css and predictive.css (the pages reuse
   their panel, kpi, table, pdm-input, pdm-bar and pdm-status rules). */
