Chat can feel off-center in the space beside an open thread details card (#29081), while other users prefer the current canvas alignment.
Change
Add Appearance → Center chat beside thread details, defaulting off, so users can opt in without changing the default layout from #25838.
The preference follows existing client persistence, hydration, settings search/command palette, and per-setting/global reset behavior. It applies to the shared web/desktop chat canvas; mobile has no inline details card.
Scope
This adds a scoped appearance feature for #29081, keeping both alignments available as requested in this PR. Default-off preserves main’s intentional canvas centering while allowing the issue’s preferred layout. Fixes#29081.
Verification
merged main 9bea6f7eb0de without rebasing. resolved the canvas test conflict by preserving both main's narrowest-width popover assertions and this pr's opt-in centering assertions. head: ff2db19236038a6d4f1e74b5108a838153186ab0. no product behavior changes were added in this takeover.

verified the opt-in switch through the real web client with the free replay provider on isolated state, using playwright and google chrome. the same conversation shifts beside details when enabled, returns to full-canvas centering when details close, and restores the opt-in layout when reopened. the preference persisted after reload; its reset restored the default. checked inline details at 1300px, popover at 1200px, and inline restoration at 1675px. uploaded images loaded at full resolution; video playback and seeking were verified.
the bot's remaining issue-link concern is a product decision about opt-in behavior; the setting preserves the requested choice between both alignments. the pr's documented rare tall-preview anchor limitation remains accepted and unchanged. native desktop, mobile devices, other providers, and relay/tunnel modes were not exercised in this pass.
Macroscope's review found this PR approvable — Centers the timeline and composer beside an open thread-details card while retaining existing spacing constraints. The change is limited to visual layout, with no persistent-data or external-system effects.

A new client setting controls whether the chat is centered relative to the left edge of an inline thread details card. The setting defaults to false. Appearance settings provide a switch, search entry, and reset behavior.
Changes: Chat centering setting and layout
Layer / File(s)
Summary
Setting contract and appearance controls packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts, apps/web/src/components/settings/AppearanceSettingsPanel.tsx, apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts
The client setting defaults to false and supports optional updates. Appearance settings expose the switch, search entry, changed-setting label, and reset to the default. Contract tests cover the default, patch omission, and encoding.
When enabled and an inline details card exists, the chat layout uses the card’s left edge as its centering reference. Otherwise, the existing container reference applies. The canvas passes the setting into the layout model. Tests cover positioning, card mode, and preview placement.
This adds an opt-in appearance setting that is off by default, so existing chat alignment is unchanged unless a user enables it. No merge-blocking risk was found.

Explanation
The title "feat(web): add opt-in chat centering beside thread details" names the main change: a default-off Appearance setting that centers chat beside the open thread details card. It follows the conventional commit style the template asks for. The changeset matches it: the layout resolver, canvas model, ChatView/ChatCanvas wiring, the settings schema and panel, and the search entry all implement this opt-in.
Full details: Out of Scope Changes check
Explanation
The changes fall into three groups. The first group changes the layout calculation in chatCanvasLayout.ts, canvasStore.ts, ChatCanvas.tsx, and ChatView.tsx. This group implements the centering requested by #29081. The second group adds the centerChatBesideDetails client setting in packages/contracts/src/settings.ts. This group supplies the gate for the layout change. The third group covers persistence, the Appearance settings control, reset behavior, and settings search in AppearanceSettingsPanel.tsx, SettingsPanels.tsx, and settingsSearch.ts. These pieces expose the gate in the UI. They do not add behavior outside the chat canvas centering. No unrelated files appear in the summary. Settings UI scope is larger than the bug fix, but the PR describes it as the mechanism for the opt-in layout, and #34108 requests the same choice.
Full details: Description check
Explanation
The description follows the repository template. It states the problem (chat off-center beside an open thread details card, issue #29081) and the change (a default-off Appearance setting, Center chat beside thread details). It covers scope with a linked issue, and it gives detailed verification: tests, a changed-file check run, and manual real-client checks at several widths. It includes before/after screenshots and a GIF. Minor gaps: the Problem section is brief, the Scope section justifies a feature for an issue even though the template says bug fixes only, and the template asks for the model and harness used, which the author gave (gpt-6.1-sol via Codex/T3 Code). Those gaps do not make the description largely incomplete.

Explanation
Issue #29081 expects the timeline and composer to center in the free space beside the sidebar and the open details card by default. The current PR adds centerChatBesideDetails, defaulting to false in packages/contracts/src/settings.ts. resolveChatCanvasLayout in apps/web/src/components/chat/chatCanvasLayout.ts applies the card-left centering only when this setting is true. With the default value, the reported misalignment remains for all users. The opt-in path does implement the requested centering: the new layout test asserts a 324px end inset beside the card, and the Real-client measurements report x=382 to x=236 at 1500px. The requirement is met only for users who enable the setting. The previous assessment (default centering, PASS) no longer matches the current code. Scope of the default is a product decision. The PR description cites #25838 for the current default and discussion #34108 for the opt-in request. Those sources do not change the expected behavior stated in #29081.
Resolution
Make the card-beside centering the default behavior for the desktop/web chat canvas, so the default centerChatBesideDetails value produces the layout described in #29081. Keep the existing full-column centering when the details card is closed. Update the default-value tests in packages/contracts/src/settings.test.ts and the layout tests in chatCanvasLayout.test.ts and canvasStore.test.ts to match. If maintainers decide that default-off is the intended product behavior, they must revise #29081 or close it with a different scope before this PR can satisfy the linked issue.

Heads-up: this changes the same centering line as #34108, which asks for the opposite (keep the Comfortable-width chat centered in the window when the sidebar or details card opens). Could this land behind a setting so both behaviors stay available?
