fix(desktop): keep sidebar artwork out of the drag region

[Gigioxx]

What Changed

Reset -webkit-app-region to initial on the shared sidebar artwork. This prevents the artwork from inheriting the header's native drag region.

Why

The 80px artwork extends below the 52px header and covers Search and New thread. Electron inherits app-region: drag through the artwork, so native pointer events never reach those controls, while the keyboard shortcut still works. pointer-events: none does not exclude a native drag region.

Use initial because Electron maps an explicit none to no-drag, which would cancel dragging across the overlapping header. The reset keeps the header at drag and the artwork at the initial none value. Development and nightly artwork share this fix.

Fixes #10661.

Verified with Electron 44.1.0 on macOS using isolated state copied from an existing profile: native pen clicks open the project picker, Search accepts typing, and repeated clicks work after dismissal. Restoring the original inherited style reproduces the blocked pen with no pointer events; Cmd+N still opens the picker. Linux/Hyprland and Shift-click were not exercised. Web build, scoped formatting, and git diff --check pass. No JavaScript, provider, or contract changes.

UI Changes

Cropped to omit project paths and thread content. Before restores the original inherited style; after uses the compiled fix.

Before: native click ignored	After: native click opens picker

Note

Reset -webkit-app-region on sidebar-stage-backdrop utility

The sidebar stage artwork was inheriting the titlebar's native drag region, making it uninteractable. Adds a WebKit app-region reset to the sidebar-stage-backdrop CSS utility in index.css so those elements use the initial app-region value instead.

• line 407: -webkit-app-region: initial only resets the artwork to the property's initial value; it does not create the no-drag exclusion Electron requires. The backdrop is a child of the .drag-region header and overlaps controls below the 52px header, so the ancestor's rectangular draggable region still covers that area and native pointer events remain suppressed. Electron documents app-region: no-drag as the operation that excludes an overlapping rectangle and reenables pointer events. [ Out of scope (triage) ]

Approvability

Verdict: Approved at 994a6cd

Macroscope's review found this PR approvable — This is a one-file, two-line desktop CSS fix that confines the sidebar artwork's native drag-region behavior without changing application logic or contracts. Its runtime effect is limited to restoring pointer interaction in the affected sidebar area.

Explanation

The change directly targets issue #10661, but the issue reports a Linux/Wayland failure and requires normal and Shift-click behavior. The PR verifies only macOS, does not verify Linux or Shift-click, and the review note questions whether initial excludes the inherited draggable region.

Resolution

Validate the fix on Linux/Wayland with normal clicks, hover, and Shift-click. Confirm that the artwork no longer suppresses pointer events while header dragging remains functional. If initial does not provide the required exclusion, use an implementation that explicitly creates the correct non-draggable region.
