/* ==========================================================================
   Pascoe Business Systems - site stylesheet

   The palette comes from the approved brand pack
   (06_COLOUR_THEME/PBS_THEME_TOKENS.json): navy #071E3D and accent #F5A516.

   Two surface systems, matching the two approved logo systems:
     .surface-light  light ground, navy type, amber used sparingly
     .surface-dark   navy ground, light type, the metallic logo

   Amber is never used for small text on white: #F5A516 on #FFFFFF is about
   2.1:1, well under the WCAG AA threshold. It carries buttons (with navy
   text), rules, marks and large display accents instead.
