[css-color-5] Example 11 cannot use source color channel keywords

[cdoublev]

I think oklab() cannot use c and h in Example 11 for RCS:

html { --base:  oklch(52.6% 0.115 44.6deg) }
.summary {
  background:  oklab(from var(--base) l c  calc(h + 90));
}

Correct. (It clearly intends to use oklch() in both instances.)

Wow that looks like a copy-paste error to me! Probably my fault from a recent edit. the oklab should be oklch.

(And yes, obviously)
