expands the table https://drafts.csswg.org/mediaqueries/#mf-interaction to include an example of
pointer:none
, swaps "stylus-based screen" to "stylus digitizer" (preferred/common term), adds distinction between basic and advanced stylus (the latter does support hover)adds an introductory paragraph in the main "Interaction Media Features" section that introduces the concept of primary/all input mechanisms
based on the conversation in [mediaqueries-4] Interaction Media Features make a rigid primary/"rare" distinction #690 (comment), add a (non normative) note hinting at ways in which UAs can potentially determine what is and isn't primary (based on @frivoal's explanation to me in that thread about what the expectation for UAs seems to be...this makes it a bit more explicit)
both these changes should be editorial, rather than substantive, as they don't introduce any new normative requirements.
this addition would, as far as i'm currently concerned, close #690
