/* =====================================================================================
   StaffJunction - flat design system (§12.1, §12.7)
   =====================================================================================

   Rules taken directly from the client's flat-design reference and applied without
   exception:

     box-shadow: none            - surfaces are separated by 1px borders and whitespace
     solid colour backgrounds    - no gradients anywhere
     border-radius: 0-4px        - 8px only for the icon tiles, as in the reference
     hover = colour/opacity shift - no transforms, no depth, ~150ms

   Two deliberate additions to the six-colour reference palette, both driven by
   requirements rather than taste:

   1. A semantic ERROR RED. The reference palette's warm colours are orange and amber, so
      "expiring soon" and "expired/failed" would sit two steps apart on the same hue. On a
      compliance dashboard that ambiguity is a safety problem, not an aesthetic one - an
      expired right-to-work check must never read as merely "expiring" (§12.7 recommendation,
      flagged for design sign-off).

   2. Darkened variants of blue and red for TEXT-BEARING FILLS. White text on the brand blue
      #2196F3 measures ~3.1:1, below the WCAG 2.1 AA threshold of 4.5:1 for normal text
      (§12.5). The brand hues are kept for accents, borders, focus rings and flat areas; the
      700-weight variants carry white text. Where a brand fill must stay exact - green, amber,
      cyan, orange - dark text is used instead, exactly as §12.7 instructs.

   Every status in this system is conveyed by colour AND an icon AND a text label, so it
   survives colour blindness and the greyscale printing of an evidence pack.
