/**
 * Helpers for decoding GoTalk NOW's NSKeyedArchiver-encoded values.
 *
 * GoTalk NOW stores UIColor and UIFont objects inside `<data>` tags as
 * binary property lists (NSKeyedArchiver). Rather than pulling in a full
 * bplist parser, we exploit the fact that the archived objects embed
 * human-readable ASCII representations of the component values, e.g. an
 * NSRGB colour appears as "0.908 0.355 0.522" and a font name appears as
 * "Futura-Medium".

/**
 * Decode an NSKeyedArchiver-encoded UIColor into a #rrggbb hex string.
 *
 * NSRGB / NSCalibratedRGB colours store a human-readable "R G B [A]" string
 * (e.g. "0.908 0.355 0.522") inside the archive — this is the only encoding we
 * can reliably read without a full binary-plist parser. NSWhite and
 * UISystemColor values store their components as raw IEEE-754 floats, so we
 * return undefined for those rather than risk an incorrect colour.
