/* ==========================================================================
   Data Insights North West — design system
   --------------------------------------------------------------------------
   One coherent system. The previous stylesheet had a "v2" block appended that
   overrode "v1", which is what put every intro paragraph in a white box with a
   coloured left border and gave every card an arbitrary green/amber top edge.
   Colour here only ever carries meaning: green = primary/interactive/positive,
   amber = the "before" / manual / attention state, red = loss or error.

   Chart palette is validated (dataviz six checks, light mode, #FFFFFF surface):
     categorical  #0F7A52 #D98A2B #2F6FB5 #C9455A #6B4E9E
                  — worst adjacent CVD dE 13.3, normal-vision dE 20.4
                  — #D98A2B is 2.76:1 vs white, so it always carries a direct
                    label; it is never identified by colour alone
     sequential   #6BBE9B #3AA57C #178A5F #0B6B49 #073F2B (ordinal, all pass)
