Restyle the standalone Windows tab strip with equal-width tabs that fill the row, centered Segoe UI titles, theme-derived selection/hover/divider colors, right-side hover close buttons, and a right-edge new-tab button. The native caption remains separate from the tab row.

Use the same close rectangle for painting and hit testing. Drag reordering follows actual tab rectangles, including the remainder pixels distributed across fitted tabs. Two geometry regressions cover fitted/overflow layouts and all 64 nonuniform drag thresholds.

Native Windows verification passed 21 checks across dark opaque, opacity 0.8, and light fixtures: independent PTY input, tab switching, mouse hit targets, creation/closing, persistent titles, normal shutdown, and successful exit status. The test stages the executable, matching console runtime, and portable resources under a local Windows temporary directory. It validates owned HWNDs and uses no global input or foreground requests.

Existing tab-overview and visibility regressions also passed (12 and 18 assertions). Captures validate the GDI tab strip; they do not establish OpenGL compositing behavior. Minimum-width overflow and cross-monitor DPI handling remain existing limitations.

Native test:

pwsh.exe -NoProfile -ExecutionPolicy Bypass -File test/win32/test_tab_bar.ps1 `
  -ExePath "$PWD/zig-out/bin/ghostty.exe" `
  -ResourcesPath "$PWD/zig-out/share" `
  -OutputDirectory "$env:TEMP/ghostty-tab-bar-proof" -Case all
