/* ===== Collapsible left sidebar =====

   The sidebar is fixed to the left edge, below the brand stripe. Its width
   (and the label visibility) is driven by a `sidebar-expanded` /
   `sidebar-collapsed` class set on `#mainContainer` from a dcc.Store via
   clientside callbacks. The main content (`#mainContainer`, see styles.css)
   shifts its left margin to match, so the sidebar never overlaps the content.
   Colours come from the tokens in alitiq-brand.css. */
