/* ── Browsing Growel's own masters: the raw-material tree ──
   The Tally masters browser's shape (.mlayout / .bookrail in tally_browse.css)
   one domain over — tree on the left, the picked material's detail on the
   right. Its own prefix rather than a reuse of .mlayout: that file's selectors
   are documented as staying under .mlayout so its short names cannot leak, and
   borrowing the container would drag .bookrail / .mtab styling in behind it.

   No colour is spelled out here that is not one of the paper-palette variables
   at the end of layout.css — nothing must reach back for Bootstrap's blue.
   Every selector sits under .orglayout, .orgtree or .orgpane so the short names
   (.caret, .on) cannot land on anyone else's page. */
