# ZB.MOM.WW.Theme

Shared UI kit (Razor Class Library — Technical-Light tokens, IBM Plex, side-rail shell, widgets) for the **ZB.MOM.WW SCADA family**; five consumers. Build/test from this directory: `dotnet test`. Component spec + gaps: `../components/ui-theme/`.

### Component-table row as it read in the index

| Component | Status | Goal | Design | Implementation |
|---|---|---|---|---|
| UI Theme (layout / tokens / components) | Adopted (feed `0.2.0`–`0.4.1`). **`0.4.0` (2026-08-11) upstreamed the Bootstrap `.btn`/`.btn-sm` sizing block** that all **five** consumers had independently written into their own stylesheets (Bootstrap hard-codes `--bs-btn-font-size: 1rem`, oversized against the kit's 0.9rem body) — sized by `--bs-btn-*` variable override **only**, never by redeclaring box properties, because `.btn-group`'s seam/radius machinery reads those same variables and a literal `font-size` at equal specificity silently flattens `.btn-sm` into a padding-only difference (a real defect found in mxgw's local copy). Same release added the `rail-btn-block` full-width rail-foot modifier; **`0.4.1` fixes it** — 0.4.0 shipped `width: auto`, which fills for an `<a>` but shrink-wraps a `<button>` (measured 114px short in the same rail), now `calc(100% - 1.2rem)` to clear `.rail-btn`'s side margins. **Consumers are five, not four** — the ignitionoee router joined. **All five consumers are on `0.4.1` and all five are PUSHED** (2026-08-11): ignitionoee `main @ 38aa5c1`, OtOpcUa `master @ e82881c1`, mxgw `main @ 0a9715d`. The two whose sweeps were not deploy-ready pushed to **branches**, deliberately leaving their default branch untouched: HistorianGateway `dashboard-ui-sweep-theme-0.4.1` — **MERGED to `main` (ff to `e42ff31`) + pushed 2026-08-13**, carrying Theme 0.4.1 + Health 0.3.0 + Secrets 0.6.2 + Auth 0.2.1 and ScadaBridge `ui/central-ui-cleanup-sweep @ 9e243493` (`main` was then `b6f383a2`). **ScadaBridge's caveat is now CLOSED and its sweep is merged, deployed and live** (2026-08-11): the branch landed on `main`, and the two follow-ups `d14e0ee4` + `3eb7df74` fixed exactly the four detail-modal surfaces the caveat named — the modal is now gated on **user intent (the held id)**, never on the row still resolving, so a background refresh that drops the row leaves it mounted and says why the summary is missing instead of unmounting the subtree and disposing Close's own handler mid-click. That disposal *was* the intermittent `GetRequiredEventBindingEntry`, and `NotificationReportDetailModalTests.Modal_StaysOpen_WhenItsRowLeavesThePage` now pins it. **Deployed to wonder-app-vd03: OtOpcUa `e82881c1`, and ScadaBridge `3eb7df74` (2026-08-11 — theme.css/layout.css/nav-state.js served from `_content/ZB.MOM.WW.Theme` and referenced by the pages; all six changed routes 200). HistorianGateway on wonder still runs `e9c31da` = Theme 0.3.1 — its 0.4.1 is now on `main` (merged 2026-08-13) but not yet deployed to the box.** **On bump, TRIM the local `.btn` block, don't delete it** — four of the five were pure sizing, but mxgw's also carried `border-radius`/`font-weight`/`white-space` that a blind delete would have dropped. | Shared `ZB.MOM.WW.Theme` RCL | [`components/ui-theme/`](components/ui-theme/) | [`ZB.MOM.WW.Theme/`](ZB.MOM.WW.Theme/) |

### Narrative

The UI-theme component is fully populated: a normalized [`spec`](components/ui-theme/spec/SPEC.md),
a [`design-tokens`](components/ui-theme/spec/DESIGN-TOKENS.md) reference, a
[`shared-contract`](components/ui-theme/shared-contract/ZB.MOM.WW.Theme.md), three
[`current-state`](components/ui-theme/current-state/) docs, and an adoption [`GAPS`](components/ui-theme/GAPS.md)
backlog. Shared = Technical-Light tokens + IBM Plex fonts + side-rail shell + widgets; left
per-project = each app's `site.css` page layout, route content, scoped `.razor.css`.

The shared RCL is **built and lives in this repo** at [`ZB.MOM.WW.Theme/`](ZB.MOM.WW.Theme/)
(.NET 10 Razor Class Library; single package; 48 bUnit tests (re-verified 2026-08-11 at `0.4.1`); feed carries `0.2.0`–`0.4.1`,
**published to the Gitea feed**). The build plan is at
[`docs/plans/2026-06-01-zb-mom-ww-theme-shared-library.md`](docs/plans/2026-06-01-zb-mom-ww-theme-shared-library.md);
the adoption plan at [`docs/plans/2026-06-03-ui-theme-adoption.md`](docs/plans/2026-06-03-ui-theme-adoption.md).
**Adopted across all three apps on 2026-06-03** (full canonical cutover, SPEC §7) on each repo's
`feat/adopt-zb-theme` branch — committed + spec/code-reviewed, then **fast-forward-merged into each repo's local
default (master/main) and PUSHED to origin (gitea)** (in sync; `feat/*` kept locally as history): OtOpcUa
→`lmxopcua` `master`@`11de14d`, ScadaBridge `main`@`58352a6`, MxGateway→`mxaccessgw` `main`@`73e54e2`. The `0.1.0 → 0.2.0` bump first promoted nav-expand persistence
into the kit (`NavRailSection.Key`/`data-nav-key` + a localStorage `nav-state.js` enhancer emitted by a new
`<ThemeScripts/>`), so all three apps share one persistence mechanism (OtOpcUa's bespoke cookie/JS-interop nav
island retired); MxGateway additionally gained a net-new Blazor `<LoginCard>` `/login` page over its existing
hardened endpoint. Per-app result in [`components/ui-theme/GAPS.md`](components/ui-theme/GAPS.md).
Build/test from `ZB.MOM.WW.Theme/`: `dotnet test`. Consumer matrix: all three apps consume
the single `ZB.MOM.WW.Theme` package (OtOpcUa AdminUI, MxGateway Server, ScadaBridge Host + CentralUI).
