MacOS: Terminal window shadow inconsistent with system setting (warning, super nitpicky)

[lucsky]

Note: I initially discussed this problem in this Discord help thread but I create this discussion to potentially escalate it to an actionable issue, let me know if you want me to also migrate the various screenshots.

The gist of it is the following:

• On MacOS, Ghostty uses an extension to NSAppearance which dynamically adapts itself based on the theme background color when the window-theme is set to auto.
• In my case, my MacOS system is set to light mode but I am using a dark theme in Ghostty (catppucin-frappe) so because of the aforementioned NSAppearance extension the terminal window gets the dark mode shadow, which is much stronger than the light one (see screenshots in the help thread, told you it was massive nitpicking).
• A potential workaround is therefore to explicitly set the window-theme to light which does work and make terminal windows adopt the "correct" shadow.
• However this causes another bug: tab titles are now rendered in black, which in the case of a dark background is an obvious problem (again, you can see a screenshot of this in the Discord help thread).
