/* =====================================================================
   UTL ERP - "Slim" theme (2026-10-09)
   One colour family: navy + its shades, white, cool greys.
   The only other colour is a muted red, kept for errors / danger.
   Loaded by erp/layouts/base.html AFTER its own <style>, BEFORE each page's
   {% block extra_css %} - so a page can still override it.
   Everything is scoped to body.theme-slim (header toggle Slim / Classic)
   and to @media screen - print and PDF output are not touched.
