/**
 * X11 colour names, as OSC 10/11/12 accept them.
 *
 * A terminal may answer a colour query with a name rather than an `rgb:` triplet, and `xterm` and
 * friends accept one when setting. The values track the X.Org server's `rgb.txt` (v21.1.16).
 *
 * Kept in its own module because most callers never resolve a name and should not carry the table.
 * Names are stored without spaces and in lower case; {@link x11ColorToHex} normalises its argument
 * the same way, so `"alice blue"`, `"AliceBlue"` and `"ALICEBLUE"` all resolve.
