+// Color roles for the reader. These use the terminal's own ANSI palette
+// (colours 0-15) and text attributes rather than fixed hex values, so the
+// reader respects whatever colour scheme the terminal is configured with
+// instead of forcing one. Verse body text takes the terminal's default
+// foreground (most legible). The header and footer bars use reverse video
+// (the terminal's fg/bg swapped) so they stay readable on any theme -- no
+// faint text on a fixed grey bar. NO_COLOR still degrades everything to
+// plain text automatically (termenv's profile falls back to Ascii).
