/* navbar.css -- the thin top bar shared by the tutorials, the circular-flow visualizer
   (includes/flow_body.php) and the balance-sheet visualizer page (Plan F stage 6, 2026-10-17).

   Loaded AFTER flow.css on the flow pages, so these rules win there; the balance-sheet page
   loads it after common.css. Visual only: #navRegion keeps its 1.5em height because the stage
   regions below it are placed at a hard-coded top:8.5em (flow.css), and every id that JS binds
   to is unchanged. The page-number buttons and text-size controls are tutorial-only and stay
   in flow.css. */
