/* ----------------------------------------
   Layout containment — three-layer fix
   Problem: BB renders the nav + grid inside a flex-direction:row outer box.
   The grid's BB box module and html module both default to flex-basis:auto /
   min-width:auto, allowing the CSS grid's intrinsic width to balloon and
   overflow left over the nav column.
   Fix at every level of the chain:
     1. The BB box module wrapping the grid  → overflow:hidden + flex fill
     2. The fl-module-html inside it         → same
     3. The .resource-grid itself            → width:100% + min-width:0
