/* ==========================================================================
   Client Onboarding Kit — directly-editable document sheet (block: ob-doc).
   Restyled to the owner's shipped document design language (source of
   truth: "Invoice app redesign/Invoice Template.dc.html"): #FDFCFA sheet on
   an #EDEAE4 page, Newsreader display titles, circular accent monogram,
   10px small-caps eyebrows (13px mobile floor), #EEEAE2 dividers, #F4F0E9
   highlight boxes, #9A4A28 default accent (user-overridable via the
   --ob-doc-accent custom property set from JS).

   The --ob-* names below are thin aliases of the SHARED main.css redesign
   tokens (landed by the invoice worker; incl. the WCAG-corrected muted
   #756E62 / faint #7A7368 and the self-hosted Newsreader @font-face) so
   this block consumes the shared palette from one indirection point.

   File 1 of 2: sheet, inputs, tabs, masthead, identity row.
   Sections/rows/lists/footer live in onboarding-doc-sections.css.
