/* ==========================================================================
   Southland Load Board — application design system
   --------------------------------------------------------------------------
   Layering model (see docs/54_Prompt16K_UI_Completion.md):

     1. wwwroot/bootstrap/bootstrap.min.css   vendored Bootstrap 5.1 — grid,
                                              utilities, component skeletons.
     2. wwwroot/app.css (this file)           Southland tokens + the component
                                              layer built on top of Bootstrap.
     3. *.razor.css                           CSS isolation, shell only
                                              (MainLayout / NavMenu).

   Bootstrap 5.1 does NOT theme its components from --bs-* custom properties the
   way 5.3 does, so component colours are re-declared here against Southland
   tokens rather than assigned to Bootstrap variables.

   RULE: components must not hard-code colour, spacing, radius or shadow values.
   Add a token here and reference it. Razor files should carry classes, not
   inline style attributes.
