   Code Lodge — Design System
   Canonical brand tokens shared across Code Lodge apps.

   Drop-in usage:
     <link rel="stylesheet" href="design-system.css" />

   The :root tokens define the palette, type scale, radii, shadows
   and motion. Component classes (`.cl-btn`, `.cl-card`, `.cl-nav`,
   etc.) compose those tokens so an app's landing page or marketing
   site can stay on-brand without re-implementing the look.

   Source palette: includa.app — extracted to a public design system
   so shellwright.app, includa.app, tickwise.app and any future
   Code Lodge product can ship with one identity.
