OK, adjusted public-inbox.org config and all the .onion mirrors.
No code changes were necessary.

The "ui.systemUsesDarkTheme" integer pref in FF 67+
"about:config" can be used to set/override the dark theme detection:

	0: light
	1: dark
	2: unspecified, dark with the following config

The relevant part of ~/.public-inbox/config looks like this, now:

	[publicinbox]
		css = /path/to/public-inbox/contrib/css/216dark.css \
			media=screen
		css = /path/to/public-inbox/contrib/css/216light.css \
			media=print

		; added this line for FF 67+ users:
		css = /path/to/public-inbox/contrib/css/216light.css \
			media='screen AND (prefers-color-scheme:light)'

("!important" sample patches on the way)
