/* ============================================================
   Library (next) — Policies & Procedures (#/policies, #/policy,
   ?id=<policy> reading view, ?view=approvals) and the F-tag library
   (#/knowledge, #/ftag-library).
   Loads after ivy-refresh.css and uses its tokens (--bg, --card, --line,
   --teal, --danger, --warn, --ok, --fg, --muted ...). The few colors the
   refresh does not name yet are tokens on :root below; the screen files
   carry none. Every selector is scoped under .lib (one class on each
   screen's root) so other screens are untouched. policies.js still
   injects its older #pol-styles block after this file, so rules that
   restyle a pol-* class carry the .lib scope to win on specificity.
