Some more resources people pointed me to:
My chum and co-author Remington Sharp tweeted
We need a universally recognised icon/image/logo for "works offline".
Like the PWA or HTML5 logo. We need to be able to signal to visitors that our URLs are always available.
To the consumer, the terms Progressive Web App or Service Worker are meaningless. So I applied my legendary branding, PR and design skills to come up with something that will really resonate with a web user: the fact that this app works online, offline – anywhere.
So the new logo is a riff on the HTML5 logo, because this is purely web technologies. It has the shield, a wifi symbol on one side and a crossed out wifi symbol on the other, and a happy smile below to show that it’s happy both on and offline. Above it is the acronym “wank” which, of course, stands for “Works anywhereno kidding!”

Take it to use on your sites. I give the fruits of my labour and creativity free, as a gift to humanity.
