+# rainbow-dark.theme
+#
+# A dark-background irssi theme that leans into a full rainbow for
+# highlights, nicks, and statusbar accents. Reads best on a true-black
+# or near-black terminal background (e.g. xterm-256color, 80% opacity,
+# no bright-bold forced to normal weight).
+#
+# Activate:
+#   /set theme rainbow-dark
+#   /save
+#
+# When testing changes: /RELOAD picks up edits without restarting irssi.
+# Remember to /SAVE before /RELOAD — /SAVE will overwrite this file
+# otherwise. Keep a backup.
