/* ==========================================================================
   VIT HR — portal landing page
   --------------------------------------------------------------------------
   Layout and component anatomy follow the VNPF One portal (vnpf.one), which
   is entirely token-driven; the brand ramp is swapped for VIT's navy and
   signal yellow. Yellow is a non-text accent only: #f6c515 on white is
   ~1.6:1, so every text/interactive colour is navy.

   Contrast (WCAG 2.1):
     --brand       #082b55 on #fff  13.9:1   AAA
     --brand-dark  #051d38 on #fff  16.6:1   AAA
     --ink         on --brand-light 12.8:1
