```

Please be careful to avoid 'straw man' arguments. I don't think any of
 these hold up to scrutiny, but I'll respond to the first two:

1. You suggested: `increased-contrast-preference: decrease; /* night 
mode */` Given the broad range of contrast settings across 
implementations, I doubt we'll ever be able to standardize a single 
generic "increase contrast" setting. If anything, it's likely to be 
several more granular such as `prefers-reduced-transparency`, 
`prefers-minimum-contrast-ratio`, etc. It also seems likely that a 
"night-mode" media feature could be separate.

2. You suggested: `reduced-motion-preference: double; /* motion okay 
but I want them very fast */` This again seems unlikely to me, but if 
needed, seems better as a timing preference specific to transitions, 
rather than all motion. Maybe `prefers-minimum-transitions: 
no-preference | immediate | fast`? (Note: Not an endorsement.)
