The rollup json plugin allows accessing keyss with named exports,

More in line with native button elements

Add anew one since this adds some default padding and I don't want to
break existing layouts by changing the normal button.

If we figure out a way to keep the layout the same without changing

This way we can change the full path/namespacing at a later point.

These allow linking multiple AbortControllers and ceate a timeout abort signal.

For example in case you want to abort a fetch in case

(1) the UI element gets removed
(2) a newer request replacing this one gets started
(3) a timeout happens because the fetch takes too long

createLinkedAbortController() allows merging multiple signals into one
and createTimeoutAbortSignal() allows creating a singal that auto aborts
after some time passes.
