/* ======================================================================
   Hoffman UI v1
   ----------------------------------------------------------------------
   Shared design system for every Hoffman internal app. Served by the
   portal at /static/ui/v1/ui.css. Sub-apps link to it via root-absolute
   path; nginx routes /static/* to the portal in production.
   ----------------------------------------------------------------------
   Canonical source:    portal/src/portal/static/ui/v1/ui.css
   Macros + base.html:  portal/ui-source/v1/
   Sync to apps (dev):  scripts/sync-ui.sh
   ----------------------------------------------------------------------
   To edit: change this file, commit + redeploy portal. Production picks
   up the change instantly across every sub-app (no app redeploys).
