/**

* Whitepoint reference values — CIE standard illuminants (A, B, C, D50-D75, F1-F12,

* E) for both the 1931 2° and 1964 10° observers, XYZ scaled to Y = 100. Split out

* of xyz.js so that spaces which never touch the table (most of the library) don't

* carry it in tree-shaken bundles — import it only when you need an illuminant.

*

* import whitepoint from 'color-space/whitepoints.js'

* whitepoint[2].D50 // → [96.422, 100, 82.521]
