+# SYNOPSIS
+#   __config_toggle_draw <cur_row> <cur_scope> <var1> ... <var7>
+#
+# DESCRIPTION
+#   Renders the 14-line config-toggle TUI panel to stdout. Intended to be
+#   called once on startup, then again after each keypress preceded by
+#   `printf '\e[14A\e[J'` (cursor-up 14 lines + clear-to-end) to redraw
+#   in place. Does not move the cursor — caller manages positioning.
+#
+# ARGUMENTS
+#   cur_row    0–6, the currently highlighted row
+#   cur_scope  "universal" or "session"
+#   var1–var7  Variable names for rows 0–6 (in order per Variable Reference)
+#
+# RETURNS
+#   0  Always
+#
+# EXAMPLE
+#   __config_toggle_draw 0 universal \
+#       __fish_config_op_aliases __fish_config_op_autoexec \
+#       __fish_config_op_overrides __fish_config_op_integrations \
+#       __fish_config_op_logging __fish_config_op_greeting \
