/* ------------------------------------------------------------------
   Finance Document — shared stylesheet for the public page and the
   staff page.

   The look is deliberately plain: a document library is something people
   scan, not something they admire. Everything here serves that — one
   accent colour, generous white space, no gradients, no shadows beyond a
   hairline, and type sizes that stay readable on a phone held one-handed
   at a counter.
