/*
  IFP Petro — enterprise UI theme (design tokens + base components)
  ------------------------------------------------------------
  Plain CSS, no build step. Every colour, radius and shadow used by
  theme-bridge.css, sidebar.css, home-dashboard.css and auth-login.css
  comes from the custom properties on :root below. The same palette is
  fed into CoreUI/Bootstrap via resources/sass/app.scss.

  Status semantics (keep consistent across modules):
    success  — available / completed / approved
    info     — informational / active / selected
    warning  — low stock / pending / needs attention
    danger   — critical / failed / rejected / destructive
    neutral  — inactive / draft / empty
