Follow-ups from the review of #34656 on the Invite People sheet (listed on #33746):

• VoiceOver skipped nothing. The invite link row stays laid out with no link so the card keeps its size, but VoiceOver still read the empty label and the disabled Copy Invite Link. Now the row, its label and the button are hidden from accessibility until the chat has a link, and come back when it does.
• Copied outlived its link. If the link went away while Copy Invite Link read Copied (the last invitee removed), the next link showed with Copied. Loading the shares now clears copied (and its reset timer) when there is no link.
• zh-Hans used 拷贝 for Copy Invite Link and Copied; the rest of the catalogs use 复制. Now 复制邀请链接 / 已复制.
• Test: the card test now checks Copy Invite Link has one fixed width that fits Copied and keeps it across the confirmation.

Commit 1 adds the tests (the accessibility and Copied checks fail on base), commit 2 the fix. Design spec: design/chat-multiplayer.md (Invite people); no design change. Localization audit: only the two zh-Hans values changed; no new strings.

Summary by cubic

Updates the Invite People sheet so VoiceOver skips the empty invite-link row, and the Copied confirmation clears when the link disappears.

• Keeps the row laid out to preserve the card's size while hiding it from accessibility.
• Updates the Simplified Chinese translations for "Copy Invite Link" and "Copied."
• Tests accessibility, confirmation reset, and button width across the confirmation state.

^{Written for commit 1f03386. Summary will update on new commits.}

Review (subagent claude-opus-5-5 medium): SHIP at 2741c67

Visual verdict: unchanged by this diff (accessibility state, two zh-Hans values, a model flag and tests; layout and alpha as on base).

Checked the NSView accessibility API names, DemandTimer.cancel(), MainActor isolation, that the accessibility and Copied tests fail without the fix, and that the width checks read the one fixed width constraint linkView sets.

Follow-ups:

• [follow-up] F1 (correctness, outcome:pending): load() clears copied only when the link goes to nil; a link replaced by a different one inside the 1.5 s window still shows Copied. Clearing on any change of inviteLink would cover it.
• [follow-up] F2 (quality, outcome:pending): CmuxDialogButtonView.retitle does not call invalidateIntrinsicContentSize(); the fixed width hides it here, other users may size stale.

Review (subagent claude-opus-5-5 medium): SHIP at ae53f06

Visual verdict: unchanged by this diff (test only).

The new commit narrows the fixed-width check to the button's own required constant width (the old count also caught its subviews' width constraints, the CI red at line 464); it compiles and the frame-width checks across Copied still guard the behaviour. Compile check passed at this head.

Follow-ups: [follow-up] F1 (test, outcome:pending): !fixed.isEmpty could also check a matched constant equals the button's frame width.
