backdropGrayscale
Desaturates the backdrop toward grey (1 fully, 0 untouched) so a coloured overlay reads as the only hue in the area.

Every documented call, beside the CSS it emits.
| Call | CSS |
|---|---|
u.backdropGrayscale() | css({ "--ui-backdrop-grayscale": "1", backdropFilter: "... grayscale(var(--ui-backdrop-grayscale, 0)) ...", WebkitBackdropFilter: "... grayscale(var(--ui-backdrop-grayscale, 0)) ..." }) |
u.transparencySafe(u.backdropGrayscale(0.5)) | css({ "@media (prefers-reduced-transparency: no-preference)": { "--ui-backdrop-grayscale": "0.5", backdropFilter: "...", WebkitBackdropFilter: "..." } }) |
Using a custom value
Every scale argument also takes a raw CSS value, which passes through untouched.
