PR #3400 - ReviewStage/luke

D21 of the design-system migration (Desktop stack, base feature/desktop-d20-workspace-github-connections, #3399).

What

Linear's row in Settings › Workspace › Integrations is @luke/ui's SettingsRow:
- owner/admin: through MenuRow's row form (as Members does), led by Linear's ProviderMark in the .settings-row-mark box; label "Linear", description the line for where the connection stands
- control: Connect (none stands) or Connect again (Linear stopped honoring it) as the outline Button, replacing toolbar-button bordered-button; none while a connection is active
- Disconnect stays behind the ⋯ (and right-click) once a connection stands, asking first through ConfirmDialog
- member: a read-only SettingsRow with the same mark and line
A sign-in that could not be begun is still said under the row as .error-message role="alert", inside a .workspace-linear column, as GitHub's, API keys', Members' and Invitations' are.
With both its rows moved, the Integrations group is SettingsSection (title "Integrations"), its GITHUB_REPOSITORIES search anchor on a wrapper div, as Members and Invitations do. SettingsGroup stays for Leave and the read-failure card, which are D22's and later.
Behaviour is unchanged: Connect sends one WORKSPACE_LINEAR_CONNECT at once, asking nothing, and a second press while it starts sends nothing; Disconnect sends WORKSPACE_LINEAR_DISCONNECT after the confirm.

Selectors

.workspace-linear joins the .api-key, .workspace-identity, .workspace-member, .workspace-invite-row, .workspace-github column rule and its > .error-message rule.
Nothing Linear-specific existed to remove. LinearCopy became linearLine, the description alone.

Visible changes

Connect / Connect again use the shared outline Button face (weight 500), as GitHub's Connect does since D20.
While the browser is being sent, Connect shows the shared button's busy ring, and is named "Connecting" for that moment. Before, it was disabled with aria-busy and no ring. It still refuses a second press.
Linear's label and description use the label role (13/18, 500) and caption role (12/16), matching GitHub's row above it.
The Integrations heading and card are now the shared section's (same as Members and Invitations above it).
Below a 380px row, Connect drops below the words, per the shared row contract.

Tests

New in workspace-page.test.ts: while a Linear sign-in is held on the wire, an admin's Connect is named "Connecting" and is aria-busy. Once it lands, Connect returns to its own name, with no alert. Verified to fail with the busy props removed. This is the only user-visible behaviour change. The harness gained linearConnectHeld to hold the act; unheld, it still answers as before.
Otherwise no test changed. workspace-page.test.ts's helpers already read both shared and window rows since D20, and its Linear tests (connect once, connect-twice guard, ⋯ Disconnect with confirm, Escape returning focus to the ⋯, member read-only, unconnected wording) pass unchanged. settings-link.test.ts still lands on the Integrations h2.
pnpm check:affected exits 0.

Evidence

Captured on Linux with headless Chrome at 1280×840. The real WorkspacePage was rendered in jsdom by a throwaway, uncommitted copy of the page's test, using synthetic workspaces. Its Integrations section was placed in the built desktop stylesheet inside the SettingsPage frame. Each shot stacks three cases: Linear connected (with GitHub's connected and suspended accounts), Linear expired, and nothing connected. In the owner shot, the third case is after Connect was refused; its red line is the test harness's synthetic refusal.

	Light	Dark
Owner/admin: connected (⋯ only); expired (Connect again + ⋯); unconnected after a refused Connect
Member: connected; expired; unconnected (read only)
