Four spaces followed by a carriage return also gives a new line,
but without the spacing of a new paragraph (I included one after the comma as an example)
Yeah, typically ICC profiles are used to make colour reproduction more accurate, but it should be possible to use one to make colours more vibrant/saturated instead of focussing on accuracy, the main hurdle will be creating a profile that does this how you want. Looking online it seems there are some tools that can edit/create ICC profiles like RawTherapee's ICC profile creator and Argyll CMS, but these might be challenging to use to get the result you want.
For a simple solution you could try nVibrant if you have an NVidia GPU, or vibrant-cli if there is a Wayland compatible version (you mentioned it in your post, but from what I could find it only supports X11).
Gamescope can be run separately from Steam, but still has the issue that it will only work for whatever application is running within gamescope (unless you run the entire plasma desktop within it).
Someone has made a GLSL shader to increase vibrance, that is part of a kwin-effect-shaders project, but it hasn't been updated in 3 years. If you are going to make your own KWin script/effect, then that shader might be a good reference.
In the UK we have (in UK pints, 1 pint = 568ml): 1 pint, 2 pints, 4 pints and 6 pints. We also have slightly smaller metric sizes (1L, 2L) that are typically seen in convenience stores or on branded milk.
I would say that 4 pints (2.273L) is the typical size that most would buy for regular use, with smaller sizes popular for those that don't have cereal/porridge. I find that milk from the supermarket tends to keep well, so it's not that difficult to get through a 4 pinter, unless all you use it for is adding some in your tea - in which case you can just get a 1 or 2 pint jug.
You could probably create a colour correction (.icc) profile for this and apply that to your monitor in the settings, but I know nothing about creating ICC profiles so can't help you there
Just like Ubuntu and several other distros they have a server focused variant

Even if you check, you should download with curl and check the downloaded file, then run that, as a malicious server could present a normal download to browsers based on user agent and other fingerprinting data, while presenting a malicious script to curl
Wish people would stop suggesting the pipe to bash scripts as an install method but the simplicity of being able to tell all Linux and Mac users to just paste a string into their terminal to install and letting the script deal with any differences between systems is probably why we keep seeing it for major projects, rather than a long list of instructions for different distros
Also infuriating is when the OP gets told by a mod to stop posting AI slop comments and OP responds:
I'm explaining the project in as detailed and clear a manner as possible - using the LLM to do it. The same one that helped me build it. Shut it down then man, why warn me?
Would be nice if they supported any old flatpak, but I expect they will have their own packaging format that can only be installed from their own store and not side-loaded. They certainly will want to lock down and control what applications can do.
Depends how well they lock it down, Kindles are based on Linux and several of the recent models didn't have any jailbreaks available until winterbreak came out. Not sure if Amazon have managed to patch against it but I took the opportunity to jailbreak mine as soon as I found out about winterbreak.
Also worth noting that on the android based fire TV sticks, you can install android apps easily, not sure Amazon will give you that freedom on the Linux versions
Cost - USB-C is more expensive
And repaste it if you're going this far
