/* ==========================================================================
   WOODRUFF SAWYER DESIGN SYSTEM — SITE STYLESHEET
   Two class families live in this file:
     .dss-*  -> documentation SITE CHROME ONLY (sidebar, topbar, doc layout).
                Never reuse these in a product UI.
     .ws-*   -> the actual DESIGN SYSTEM COMPONENTS (buttons, inputs, cards…).
                These are the classes product teams should copy into apps.
