     --line-brown   #664b38 on sand   6.90:1   passes AA body text
     --text-muted   #7a6252 on sand   4.91:1   passes AA body text
     --text-subtle  #8c7360 on sand   3.83:1   LARGE TEXT ONLY (>=18px or
                                               bold >=14px) and borders
     --accent-blue  #00a0ff on sand   2.43:1   NEVER as text, never behind
                                               text. Decorative fills and
                                               canvas arrow strokes only.
     white on --accent-action #0076c0 4.82:1   passes AA. Use this for every
                                               filled button carrying a label.
     white on --accent-blue           2.81:1   FAILS. Do not pair.
