/* HTTP API — live-updates workzone diagram (lu-* pipeline strip + frames
   table). The push channel reads left-to-right in one strip — worker →
   publish → stream → client → REST — before the notes are read; the lu-tbl
   carries the event contract and the boards matrix.
   Static — no hover affordance (README §Hover).
   Loaded by _workzone/live-updates.html on top of ../../module.css.
   Placement convention: docs/architecture/README.md §Styling. */
