"Zoom in" or "buy a different monitor" is not an appropriate response to people bringing up the plethora of objective & subjective a11y issues on the page.
If you really don't care about providing an accessible experience, try this: no one will use the tool if they can't read the docs. With my monitor and eyesight, it's entirely illegible.
Neither of those things are true to my knowledge... I can find absolutely no evidence of Ryan Carniato being involved with Angular Signals (nor did I hear anything whilst they were being developed) and Preact Signals certainly weren't a port of Solid. Same name but internals share nothing and if anything, Preact's signals most closely resemble Vue's refs in API (though completely different internals -- there was no porting).
