/* Industry design system — tokens and component classes.
   Ported from the Claude Design "Industry" system so this app's CSS has one
   source of truth for color, type, spacing and the blueprint/component look.
   Barlow / Barlow Condensed are loaded via a <link> in index.html, not
   @import here — Chromium never dispatches a fetch event for @import'd
   stylesheets, so the service worker can't cache it that way. */
