Board currently shows a placeholder. This implements delivery 4 of #101 with per-group columns based on producer zones, producer-linked cards with tone and owner controls, and Done history showing the last five supplied cards. Every column preserves the producer-reported zone total and labels the supplied/filtered card count when it differs. Earlier Done cards expand through a disclosure. Each row owns its horizontal scroll; group/state filters, ungrouped work, focus keys, disclosure state and scroll positions are preserved. Owner controls open the existing actor detail. Both serving modes include the new module.

The pre-existing Team mutation has a real renderer path: initial or changed-width ResizeObserver delivery forced update(lastModel, true) even with unchanged Team facts. A deterministic regression reproduced ten counted attribute writes in the DOM fixture, consistent with the browser finding's additional reflected/dataset mutations. Geometry-driven updates now run only for Room; Team, Flow and Board use CSS layout. The Team probe additionally waits for both fixture producers and removes CSP-incompatible predicate waits. Exact macOS flake elimination remains subject to reviewer browser execution.

README and CHANGELOG describe Board and the resize fix. The README also corrects the snapshot-cache wording from the preceding PR: successful Space replies keep their existing allowlisted projection, which omits producer top-level stale/sample-time fields.

Validation at fec65df26de5b563023ec0a3340e6ba6cb0cf772:

• Frozen install passed. Focused Space/public/design tests: 73 passed on this head, including mismatched totals in Done and Work before/after filtering, with disclosure math based only on supplied cards. Earlier static-build and published 0.1.8 compatibility tests: 22 passed.
• Main and N-1 type checks, boundary, README facts, JavaScript syntax and diff checks passed. Documentation freshness still emits two non-blocking stamp warnings; stamps are unchanged.
• New Board probe covers the 16 viewport/theme/text combinations, Done total20/supplied7 with 5/7 disclosure behavior, keyboard producer navigation, unchanged writes and local horizontal scroll. Browser execution and OCR are pending reviewer verification. Full check remains hosted-CI work per assignment.

Related to #101. Room refit, server-cache changes and producer changes remain separate.
