Add a theme toggle, and fix the voice picker showing no voices
Theme toggle sits next to the settings icon. The choice starts as 'system' and
follows the OS until you press it, after which it's explicit and persisted.

An inline script in <head> stamps the resolved theme on <html> before the
first paint - resolving it from JS after load means a visible flash of dark on
the way to light. Because that attribute is always present, the stylesheet
drops its prefers-color-scheme query entirely rather than having a media query
and an explicit override fighting over the same tokens.

The voice picker was effectively empty: Chrome reports zero voices
synchronously and only fills the list when voiceschanged fires, and while the
narrator did reload them, nothing told preact to re-render - so the dropdown
kept whatever existed at construction, which was nothing. It now notifies, and
the list arrives (181 voices here).

That many voices needs shape, so they're sorted with your own language first
and offline voices ahead of network ones, then grouped into optgroups by
language. Network voices are marked as such since they're useless offline,
which for an app built to work in a field matters.

Speed and pitch are adjustable too, both fed through to every utterance.

The settings button gains a class of its own: the header now has two icon
buttons, so identifying it by .icon-button alone hits the theme toggle.
