   iso27001partners.co.uk — site stylesheet
   Layout/UX patterns follow the reference teardown in BRIEF.md.
   All copy is original. No third-party CSS is copied.

   Palette note: a colder, bluer slate with a teal accent, so this B2B build is
   not visibly the same template as the consumer sites in the portfolio. The
   diagram tokens (--d-*) at the bottom of this file are UNCHANGED, because
   those specific values are the ones that passed the dataviz contrast
   validator against these surfaces; re-tinting them would invalidate the
   check. Chrome colours above them are free to move; diagram colours are not.
