/* =============================================================================
   hr.css - the HR portal component layer.

   Mode B throughout. Rules this file lives under, from DESIGN_SYSTEM.md:

     - NO COLOUR LITERALS. Every colour is a var() from tokens.css. There is no
       new palette here, and test/hr-tokens.test.mjs fails the build if one
       appears.
     - --accent is --ink, not brand red. The only brand red on any screen is the
       top rail and the logo lockup.
     - Red means one thing in this product: over capacity, or a conflict. There
       are no answer states in an HR tool, so --wrong is free, and it is spent
       on exactly that one meaning.
     - Section rhythm stops at --s-12. --s-16 and above are Mode A only.
     - Motion: 150ms ceiling, opacity / background-color / border-color / colour
       / box-shadow only. No entrance animation on a data table.
     - Radius system: controls --r-sm, panels --r-md, the one hero card --r-lg,
       pills and badges --r-full. Applied consistently, no exceptions.
     - All numbers are mono and tabular. A payroll column that does not align is
       a payroll column nobody trusts.
