So this happened while I was up a mountain:

But the post didn’t have a demo. Last night I made one: https://cdpn.io/aardrian/debug/azZjgGZ
I grabbed Chrome Canary and set the flags.

Not only do you need the new meta:
`<meta name="text-scale" content="scale">`
You also need to not set a base font size (or set it relative) as I generally advocate:

At which point you can start with this (attached images)…

…and up with this after you scale your system text size to maximum.
In practice, this seems analogous to the Apple method to do same on iDevices using `font: -apple-system-body;` and an `@supports()` declaration.

Anyway, I promised @eric and @codingchaos last night to share it but promptly fell asleep. The electrician will be here soon, so I’m doing this in my mobile and have to edit a couple typos in this thread.
Enjoy?

It’s a post now:

712 words, but the images are huge (dimensions, not file size). I also captured fresh images (last night’s were an old version of my demo).
