Some refresh needed?

It has been 6 years since the last update, maybe it's time to refresh? In the meantime browsers evolved a lot or even came as completely new products, I suppose some behaviour you described was changed because of optimization or de-optimization, new HTML elements making requests appeared (`video`, ``), old ones got new attributes (ex. `srcset`).

I find this game quite useful in education of newcomers and reminding myself all those tricky things. Are you interested in updating this project? I could help :)

No files, tests, or entry points are identified. Review the project’s current educational content and compare its described browser-request behavior with modern browsers, including video, preload, and srcset; done means agreeing on the scope and updating the outdated material.
