   Direction: an actual cyanotype blueprint sheet. White
   drafting ink on blueprint blue. A light coral carries
   interactive text (needs to stay readable against the
   lighter field); a deeper redline red is reserved for
   drawn linework and borders, where only visual contrast,
   not text contrast, applies.
