ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This changes the floating preview’s default placement and replaces its chat-coupled layout with a shared app-wide overlay for browser and device streams. The cross-component interaction and panel-handoff changes affect existing user workflows and warrant human review. You can add or adjust custom eligibility rules. Learn more. |

- Around line 244-247: Update the overlay in PreviewMiniPlayerShell to use
Tailwind cursor classes instead of an inline cursor style. Change RESIZE_CURSORS
to map each resize direction to its corresponding cursor-* class, and apply the
mapped class—or cursor-grabbing for the move gesture—alongside the overlay’s
existing classes.

The latest code finding is addressed in One clarification on the placement suggestion: before this PR, The independent overlay does intentionally remove preview-driven chat reflow and details-card folding. As disclosed in the PR's Scope and approval section, maintainer approval for that behavior change is still pending. The Approvability and Description findings therefore remain for a maintainer decision; no approval override has been applied. |

Problem
On macOS desktop, moving or resizing the floating preview rearranges the chat and composer, can fold the thread-details card, and can strand the browser page when the sidebar toggles. Interrupted gestures can also make later hover events move or resize the preview, while collapsing the right panel delays its transition to the floating surface.
Reproduce by opening a browser page in a thread, collapsing the right panel, dragging/resizing the floating preview, and toggling the main sidebar. Interrupt a drag by releasing outside the app, then hover the frame again.
Change
Give the shared browser/device mini-player an app-wide overlay below the top bar, independent of chat layout and sidebar width. Remove preview-driven chat/composer insets and details-card folding. Geometry updates subscribe inside the shell so pointer movement does not rerender the conversation.
Keep the corner dot and expanding hover/focus/touch toolbar, with a dedicated hold-and-drag grip. Moving retains size; docking and floating again retain geometry. Pointer release, cancellation, lost capture, blur, and missing-button events end gestures. A temporary shield keeps embedded content from taking input during a gesture.
Hand the browser surface from the closing right panel to the floating player as soon as the panel becomes invisible, including while its exit animation remains mounted.
Scope and approval
One floating-preview layout/interaction change covers browser and device streams through the shared web shell; desktop wraps that UI. Native React Native mobile navigation, provider adapters, contracts, and server behavior are unaffected. The existing panel/float controls and sidebar toggle use these paths; docking, refloating, and closing remain available.
Related sidebar defect: #13776, confirmed in maintainer triage. Restoring the freely floating default is also proposed in #14935. Triage of #14929 identifies the current reflow as deliberate design; prior maintainer approval for changing that default is still pending. This PR does not claim the obvious-bug exception or treat the sidebar triage as approval for the default change.
Related alternatives: #15499 adds a persistent browser header, #15556 relaxes a degenerate drag range, and #13924 fixes sidebar-origin measurement. This patch keeps the collapsing toolbar and gives both preview sources an independent coordinate space.
