v3: kanagawa's headline stays readable on the scrim — over a photo the title rests white on black in either scheme, but hovered it took --color-accent, and Lotus's lotusBlue4 is picked to sit on warm paper: on the scrim it falls to about 3.8:1, worse where the gradient thins and the picture shows through. The ground over an image is Wave-dark whichever scheme is on, so the accent there is now Wave's too — crystalBlue, which is what the dark scheme already hovers to, so both schemes behave alike over a picture instead of one carrying a second paper-tuned blue. The overlay's resting vote button takes the same swap, ink and border, since it read the same token; the voted one keeps the true accent fill, which its pale label needs underneath it.
