/* =================================================================
   WF Portal — Side Navigation (Global)
   -----------------------------------------------------------------
   The collapsible left-rail layout. Additive + parallel to nav.css
   (the top nav): selecting which shell renders is a per-tenant choice
   (AuthState.NavLayout) made in MainLayout. Both shells reuse the same
   --theme-nav-* tokens so the rail tracks the tenant brand exactly like
   the top bar does. Styles are global (not scoped) because Blazor
   NavLink renders <a> tags outside the component CSS-isolation scope.
   ================================================================= */

/* ── Shell flex modes ─────────────────────────────────────────────
   .wf-shell is the single flex child of #app (the Blazor wrapper is
   display:contents, so .wf-shell inherits #app's flex column).

   !important on display: the framework hack `#app > div:first-child {
   display: contents }` in root.css lands on .wf-shell when Blazor renders
   the layout root directly under #app (specificity 1,1,1 beats .wf-shell).
   That dissolved the shell and dumped the rail + main into #app's flex
   COLUMN — the rail stacked ABOVE the content. Forcing display keeps the
   shell a real flex box in every render path (side row / top column). */
