A dark canvas tells you in seconds which light matters and which is noise.

Every glow on a page competes with the others. We give each screen exactly one.

Edges, reflections and one bright line do more than any backdrop filter.

We spend movement like money: a little everywhere, a lot in one place.

Blue and violet can welcome people. It is all in the neutrals around them.

Weights, widths and spacing we change when the page turns dark.
