Description

Using Spectre CSS, if you use a dropdown (.form-select) in desktop Safari MacOS, the browser will crash every time you try to open the drop down.

Here is a reproducible link, open in desktop Safari: https://jsfiddle.net/4L9zvcgr/

After hours of debugging I narrowed the issue down to the use of -apple-system, system-ui in the body font-family. Remove those 2 and it will open fine.

Here is a link without those 2 body font-family rules, which does not crash: https://jsfiddle.net/zchmf2qd/1/

Research direction
The bug is caused by ` apple system, system ui` in the body font family in Spectre CSS. Investigate the source file (likely `spectre.css` or `spectre.min.css`) to locate the specific rule. The fix is to remove or replace those font family values only for `.form select` or globally. Test on Safari desktop to confirm crash is resolved. Check if any other browsers are affected. The issue has an assignee but no linked PR, so coordinate with them if possible.
