   LBFL ACADEMIC DESIGN SYSTEM — CONV-04B
   Version: CONV-04B-1.0.0

   Activation is explicit: page.academic_system: v1.
   Every selector is scoped to html.lbfl-academic-v1. This is an owned design
   system, not a new global hotfix layer.

   A small legacy bridge uses priority declarations only to neutralize
   already-authenticated global cascade debt on opted-in academic surfaces.
   The bridge disappears
   when the legacy cascade is consolidated in later CONV-04 phases.
