   Knowsis design kit — knowsis-kit.css
   Extracted from the knowsis.net rebuild (Website_23Sep26_update, "site design v2",
   the Persona Engine look) on 30 Sep 2026. See DESIGN.md for the rules behind it.

   Purpose: one drop-in stylesheet so tools and products on the Knowsis AI server
   look like the website. The website itself keeps its own styles.css; this file
   restates the same values as tokens with a single kn- prefix.

   Folder layout this file expects (paths are relative to this file):
     assets/css/knowsis-kit.css
