   Color semantics (consistent across this piece):
     purple  = interaction / selection / javana
     lime    = bhavanga / completed / foundation
     orange  = tadalambana / test / TODO flags
     blue    = sense-cognition phase of citta-vithi ONLY
     ink     = structure, text, lines                                                     */
