/* tokens.css — the specification-bench identity for epoxyfloorcostcalculator.com.
   Olive rules, warm paper, material swatch marks, cure-stage cards. Namespace: cs-.

   FILENAME NOTE: tools/checks/check-contrast.mjs reads sites/<domain>/styles/tokens.css by
   path, and the token names it resolves are --ink, --paper, --card, --wash and --primary.
   This file is therefore named tokens.css and uses those names, so the contrast gate is
   validating the stylesheet the site actually serves. A prettier private filename would
   have left the checker inspecting an orphan file and reporting OK for the wrong reason. */
