Re: [csswg-drafts] [css-gaps-1] Asymmetric start and end offsets (#12603)

I was also in the camp of disliking `inner` and `outer` in this context, and in particular I felt `inner-outset` or `outer-inset` would be a confusing word combination. `interior` and `edge` seem to me like they would combine better with `outset` or `inset`.

I can't think of a precedent where we use "inner" or "outer" directly in a CSS property name or value, but they are used in a couple of different concepts:
- inner and outer display types, where they're about nesting rather than edge vs interior of a container
- inner and outer box shadows, where the keyword `inset` selects the former (hmm....)
- "inner size" and "outer size" are aliases of "content box size" and "margin box size" respectively in css-sizing-3, and likewise "inner edge" and "outer edge" are aliases of "content edge" and "margin edge" respectively in css-box-4

So I guess it's a mixed bag in terms of precedents. There's also `innerHTML` and `outerHTML` in the DOM. I think those, plus the display type precedent, make me still want to shy away from using `inner` and `outer` here.
