/* ============================================================
   Dossier Admin Styles
   Single source of truth for every page under /admin/.
   Linked via <link rel="stylesheet" href="/admin/style.css">.

   Palette is harmonized with dossier-landing.html. All foreground
   colors meet WCAG 2.2 AA on the #F5F0EB background; see
   DESIGN.md and CLAUDE.md for the cross-reference table.

   The --color-border stale value #D6C5A8 that appeared in some
   inline blocks has been replaced with rgba(26,26,26,0.10) here.
   The dossier-landing harmonization overrides and the WCAG AA
   btn-primary overrides are folded into the main button rules —
   no longer appended as separate cascade blocks.
