     BRAND TOKENS  -  workspace-overridable.
     A workspace owner/admin can set these three in Admin > Settings > Workspace
     Branding. Defaults below are the McKodev brand (cinnabar red + tangerine).
     theme.js recomputes the derived --primary-* / --accent-* / --bg-sidebar-*
     scale in JS when a workspace picks its own colours, so any brand still gets
     correct hover/soft/ring shades and readable contrast. We only theme the

     premium without "painting the page".
