Re: [csswg-drafts] [css-variables-2][css-properties-values] Constants in CSS (#10286)

Closest I've seen is "custom env", https://github.com/w3c/csswg-drafts/issues/2627#issuecomment-386932374.

There are also a few proposals for registering a bunch of custom properties (and their initial values) in a less verbose way.

> make sure they don't get overwritten

Does that mean you want the first rule that sets a constant to determine the value, and any further attempts to (re)set the value should be ignored? E.g.:

```
@env { --foo: 10px; }
@env { --foo: 20px; }
div {
  width: env(--foo); /* --10px */
}
```
