// Runs blocking in <head>, before the first paint.
|
|
//
|
|
// app.js is a deferred module, so anything it does happens after the browser
|
|
// has already drawn the page - which is why the theme toggle used to flash the
|
|
// wrong option on load, and why a manually chosen theme would show a frame of
|
|
// the OS one first. This has to stay a classic script with no defer/async, and
|
|
// it has to stay small enough that blocking on it is free.
|
|
//
|
|
// Absent attribute means "follow the OS", so the only work here is restoring a
|
|
// manual choice. Everything else - the pressed styling, the toggle handlers -
|
|
// is CSS and app.js respectively.
