How to fix text issue in Safari?

Question

css

Here's how it should be:

And here's how it really is in Safati:

Moreover, both screenshots were taken in safari. Text normally (not bold) in Safari only appears on one page. This page uses exactly the same styles and scripts as the other pages. Not a single difference.
In other browsers, such as Chrome, everything is fine. The problem started to occur only with Safari. Before that, everything was fine.
These two lines are basically the same

font-weight: normal;
font-weight: 400;

If you write:
font-weight: 300;
Then the text in all browsers (in Safari too) will become narrow. That's the way it should be.
Specifically these lines:

font-weight: normal;
font-weight: 400;

Safari in this case perceives the same way. Equally ignores them and makes the text obviously bolder than it should be. Again, I repeat, I check in other browsers in parallel. Everything is fine there.
What could be the problem?

Try this thing: maxvoltar.com/archive/-webkit-font-smoothing

Answer 2

Does safari have collected styles for an object? Chrome, for example, can show everything that is applied + when you click, you can see where it is. Learn, mb safari also knows how to do something like that. Those. find where the horns grow from.
Any small difference somewhere can play a role. Some kind of MB class has been added, etc.
