/* ServiceTrack - application UI system (Phase C).
   Palette matches the public landing page (navy/teal) for a consistent
   brand identity from marketing site through to the logged-in app.
   Readability rules followed throughout: dark text on light backgrounds,
   white text only on genuinely dark/saturated backgrounds, no pale-on-pale
   pairings, body text never below 14px.
   Layout note: the sidebar lives INSIDE each view's existing Bootstrap
   col-md-2 column (container-fluid > row > col-md-2 + col-md-10) - it is
   sticky, not fixed, specifically so no view file needs its markup
   changed to adopt this system. */
