+;;; test-nov-reading--config-defaults.el --- nov reading default/order tests -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Asserts the shipped reading-view defaults: a fresh EPUB opens dark, and the
+;; `c' cycle runs dark -> sepia -> light -> none -> back.  The pure-logic file
+;; test-nov-reading--palette.el covers the cycle mechanics on fixtures; this file
+;; pins the real `cj/nov-reading-palettes' / `cj/nov-reading-default-palette'
+;; values so a reorder can't silently drift the default or the cycle order.
+
