   Outsource China — corridor (category) page and the specification index

   Head with counted facts; a spec-schema filter beside the specification
   index (a real table: reference, designation, parameter columns, declared
   compliance, customisation vectors); data tiles as the alternative layout;
   the compare tray and sheet; an intelligence band under the index. Builds
   on intel.css. Also loaded by search, which uses the same index.
