The preserve option determines whether the original notation
is preserved. By default, it is not preserved.

`js
postcssColorFunctionDisplayP3Linear({ preserve: true })
`

`css
.color {
color: color(display-p3-linear 0.3081 0.014 0.0567);
}

:root {
--a-color: color(display-p3-linear 0.3081 0.014 0.0567);
}

/ becomes /

.color {
color: color(display-p3 0.59096 0.12316 0.26409);
color: color(display-p3-linear 0.3081 0.014 0.0567);
}

:root {
--a-color: color(display-p3 0.59096 0.12316 0.26409);
}

@supports (color: color(display-p3-linear 0 0 0)) {
:root {
--a-color: color(display-p3-linear 0.3081 0.014 0.0567);
}
}
`

$3

The enableProgressiveCustomProperties option determines whether the original notation
is wrapped with @supports when used in Custom Properties. By default, it is enabled.

> [!NOTE]
> We only recommend disabling this when you set preserve to false or if you bring your own fix for Custom Properties.
> See what the plugin does in its README.

`js
postcssColorFunctionDisplayP3Linear({ enableProgressiveCustomProperties: false })
`

`css
.color {
color: color(display-p3-linear 0.3081 0.014 0.0567);
}

:root {
--a-color: color(display-p3-linear 0.3081 0.014 0.0567);
}

/ becomes /

.color {
color: color(display-p3 0.59096 0.12316 0.26409);
color: color(display-p3-linear 0.3081 0.014 0.0567);
