/* Knowledge Store — data-model workzone diagrams.
   Page-bespoke pieces: the projection fan-out (ks-proj — one entity radiating
   into relational body · vector chunks · graph edges on one Postgres base) and
   the producer/keeper boundary with Harvester (dm-border). The DB-table matrix
   (dm-tbl · dm-fields · dm-c · dm-badge) and the band accent (stk-layer--ks)
   come from the module sheet ../knowledge-store.css; the bands themselves from
   ../../layered-stack.css.
   Static — no hover affordance (README §Hover).
   Loaded by _workzone/data-model.html on top of ../../module.css
   + ../knowledge-store.css + ../../layered-stack.css.
   Placement convention: docs/architecture/README.md §Styling. */
