/*
  Fix Desk stylesheet
  -------------------
  1. Design tokens (colours, spacing). Every text colour pair here was
     checked for WCAG 2.1 AA contrast: 4.5:1 for text, 3:1 for borders of
     controls and focus outlines. See the evaluation report for the numbers.
  2. Base elements and accessibility helpers (skip link, focus, sr-only)
  3. Layout: header, main, footer, grids
  4. Components: panels, forms, buttons, tags, tables, cards, dialog
  5. Page-specific pieces
  6. Responsive rules (mobile first; wider screens add columns)

  Units: rem for sizes and spacing so the layout scales with the user's
  font size and with browser zoom (tested at 200%).
  No inline styles anywhere: the Content-Security-Policy blocks them.
