/* Cache & Workers — stack.html deltas (stk-*) — the container-orchestration
   block this page adds below the swimlane stack: a heading, lead, and the
   docker-compose service table (one backend image in several roles + two Redis
   instances). The swimlane lanes, library pills, file tree, decision boxes and
   draft notice all come from the kits below — only the service-table view is
   bespoke here.
   Loaded by _workzone/stack.html on top of ../../module.css + ../../swimlane.css.
   Static blocks; .xref links and [data-tip] hover are the only interactive
   parts (README §Hover).
   Placement convention: docs/architecture/README.md §Styling. */
