#### 🎯 Subject of the issue

Experienced behavior:
The BlexMono Nerd Fonts are lighter than the IBM Plex Mono fonts on my system with the same weight name.

Expected behavior:
1:1 weight correspondence.

Extra information:
Prior to updating to KDE Plasma 6.0.1 I already had lsd set up and working with the symbols-only Nerd Font as a fallback font. For some reason that stopped working and I will have to reconfigure my fonts. While exploring the other approach (using the patched font) I noticed the mismatch in weights.

#### 🔧 Your Setup

- _Which font are you using (e.g. `Anonymice Powerline Nerd Font Complete.ttf`)?_
   - BlexMonoNerdFont-Medium.ttf (but same applies to others)
- _Where did you get the file from (download link, self patched, source downloaded from link...)_
   - https://github.com/ryanoasis/nerd-fonts/releases/download/v3.1.1/IBMPlexMono.tar.xz
- _Which terminal emulator are you using (e.g. `iterm2`, `urxvt`, `gnome`, `konsole`)?_
   - Konsole 24.02.0
- _Are you using OS X, Linux or Windows? And which specific version or distribution?_
   - OpenSUSE Tumbleweed 20240311

#### ★ Screenshots (Optional)

Above is BlexMono Medium, bottom is IBM Plex Mono Medium as obtained from the OpenSUSE Tumbleweed main repos. Both are at 10pt.
