OK, checked in edits that clarify the `central baseline` as being the ideographic central baseline. The definition in css-inline-3 now reads:

> Corresponds to the ideographic central baseline, halfway between the ideographic-under and ideographic-over baselines. 

and there are additional notes on what to do when these are missing in [Appendix A](https://drafts.csswg.org/css-inline-3/#baseline-synthesis-fonts).

@litherum @macnmm Let me know if you'd like any adjustments to these definitions?
(Also while you're staring at that Appendix, if you notice anything else wrong, please file an issue; I suspect it's overall kinda shaky.)

A follow-up question to @macnmm’s earlier comments is, do we want to suggest cap-middle as the fallback for non-CJK fonts (those that fall through to the undefined case in [OpenType's calculation](https://docs.microsoft.com/en-us/typography/opentype/spec/baselinetags#ideographic-em-box) ) instead of halfway between the ascent/descent?
