+## [1.11.0] - 2026-05-04
+
+### Added — Design-system 100%-adoption + visual upgrade
+
+The playground now consumes the shared `playground-design-system` v0.3.0 end-to-end. Plugin contract (24 commands, 12 agents, 5 skills, 2 hooks, MCP) is unchanged — playground-internal release.
+
+- **Hoisted to shared DS (v0.3.0)** — 13 generic components moved from inline `<style>` to `shared/playground-design-system/components-tier3-supplement.css`: `.eyebrow`, `.page__*`, `.key-stats`/`.key-stat`, `.verdict-pill-lg` (5-band), `.tab-list`/`.tab`/`.tab-panel`, `.top-risks`/`.top-risk[data-severity]`, `.recommendation-card`, `.card__*` subcomponents, `.card--severity-{level}`, form-patterns (`.field-row`, `.field-label`, `.field-help`, `.multi-select`, `.checkbox-row`, `.required-mark`), `.stack-lg/-md/-sm`, `.pyramide-tier-detail`, `.scenario-card-grid`/`.scenario-card[data-status="winner"]`, `.app-shell` variants. 567 new lines, 107 new selectors. Re-synced to vendored DS via `scripts/sync-design-system.mjs ms-ai-architect`.
+- **PARALLEL CSS migration** — all 6 plugin-local naming groups renamed to DS conventions: `.topbar* → .app-header*`, `.residual-pair* → .pair-before-after*`, `.command-card* / .catalog-card* → .card + .card__*`, `.screen-tabs/-tab/screen → .tab-list/.tab/.tab-panel`, `.pyramide-desc* → .pyramide-tier-detail*`. Includes markup restructure for tab-component (`data-active="..."` → `[hidden]`-attr) and pair-before-after (`data-severity` → BEM modifier). ~50 markup occurrences updated.
+- **Inline `<style>` trim** — block reduced 202 → 127 lines (~37%). `renderPageShell` + `renderKeyStatsGrid` refactored to DS markup (`.page__header-main` + `.page__header-aside` + `h1.page__title`; `.key-stat--{level}` BEM modifier).
+- **Visual upgrade (benchmarked against showcase)** — AI Act pyramid width fix (min-width 480px, font-size-md, responsive @media), severity-coded left-border on report-cards in project surface based on `parsed.verdict`, app-header restructure (brand + breadcrumb + spacer + actions), eyebrow-label "PROSJEKTER · X av X" on home, `.stack-lg` vertical rhythm on home/project/catalog body.
+- **Demo state rename** — `Acme AS` → `Acme Kommune` and `Demosystem` → `Acme Kunde-chatbot` consistently across all 17 fixtures (39 Acme occurrences). `build-demo-state.mjs` updated: `organization.name` = "Acme Kommune", `projects[0].id` = "acme-kunde-chatbot", `projects[0].name` = "Acme: Kunde-chatbot".
+- **`playground/screenshots/v1.11.0/`** — 24 regenerated PNGs (~27 MB total) reflecting the visual upgrade. v1.10.0 set preserved as historical reference.
+- **`tests/screenshot/run.mjs`** — `OUT_DIR` + comments bumped to v1.11.0.
+
+### Plugin-local survivors (intentional)
+
+Components kept inline because they are semantically distinct from DS counterparts:
+
+- `.verdict-pill` (domain go/block semantics, distinct from DS `.verdict-pill-lg` severity bands)
+- `.scenario-card[data-status="met/partial/missing"]` (DS only ships "winner")
+- `.read-more-block` + `.suppressed-panel` (native `<details>`; DS uses JS-toggled `aria-expanded`)
+- Surface-specific layouts: `.onboarding-*`, `.home-*`, `.project-*`, `.modal*`, `.command-form*`, `.catalog-cards`-container
+
+### Notes on 1.11.0
+
+- 3-session rollout (commits `40631c0` Fase 1-3 + `31aed40` Fase 4-6 + `7ffaa82` Fase 7-9). Session 1+2 committed with `[skip-docs]` because user-facing docs are bundled with the release commit.
+- Tests: 201 static + 70 parser-fixture + 7 migration = 278 PASS playground-suite, 0 FAIL. Pre-existing `tests/test-ros-output.sh` fixture-missing failure is unchanged.
+- DS bump is purely additive — other vendor consumers (okr, llm-security, ultraplan-local, config-audit) do not need to re-sync to remain green.
