Stuff on this site follows the mantra of using as few JavaScript and new stuff as deemed feasable.
Simply to maximize compatibility with browsers as old as the 3DS one and especially text browsers.
A few embedded quality-of-life tools use client-side JavaScript since this is a static website.
But all the information shall be accessible via text browsers like links, lynx, elinks, and chawan.
Leveraging this information native tools can be used to achieve the same as with the QoL tools.

Sadly, Codeberg demands up-to-date certificates. There are ways to replace them on old devices.

No third-party stuff is embedded and that's exactly why you don't see any kind of nag banner.
A cookie banner implies that somebody wants to have something you potentially don't want to share.
The EU doesn't demand cookie banners when a website doesn't track. It's as simple as that.
There is an excellect piece on this by the Commissioner for Data Protection Baden-Wurttemberg (🇩🇪).
And a small video-recorded educational lecture & game show by the same people on the GDPR (in german & with english dub).
