/* ==========================================================================
   Batowa — Toetsingskader Waterkwaliteit
   Styling for the portal and the management screens.

   Hand written, without a build step. The reason: the assessment itself is one
   self-contained HTML file with its own styling, and the shell around it is a
   handful of screens. A bundler would add an install step and a 200 MB
   node_modules without anything getting better — and would have to be run again
   on every server move.

   All colours are declared as custom properties at the top, light and dark.
   Anyone changing the house style only has to be there.

   The palette matches assets/portal.css, which the assessment uses, so that the
   portal and the assessment read as one product rather than two.
