   - `static/editor.js` (`replaceInAllChapters()`): reads `rp-current`; builds a `targets` list of either just `currentCh()` or all `chapters`, and iterates that. Shows an error ("No chapter open.") if Current-chapter-only is selected with no open chapter. Result message reads "… in current chapter" for the single-chapter case.

 - Reader: subheading/chat styling now also wins when the wrapper contains block elements with their own color rule (e.g. `<div class="subheading"><p>…</p></div>`)
   - Previously the `<p>`/`<h*>` rules in `reader.html` (`#chapter-content p { color: var(--text); }`, etc.) had the same specificity as `.subheading` and applied more directly to the inner element, so the parent's color was effectively overridden — the wrapped paragraph stayed in the default text color

 # Changelog
 
+## v0.2.12 — 2026-06-01
+
+### New features
+
+- Reader: new **Sepia** theme alongside Dark, for easier long-form reading — a warm paper background with dark brown text instead of light-on-black. A **Theme** toggle (Dark / Sepia) sits at the top of the reading settings drawer; the choice is saved per device. Text colour is now stored per theme, so each theme keeps its own tint, and the saved theme is applied before paint to avoid a flash.
+- Sidebar: the running build version is now shown at the bottom of the sidebar (e.g. `v0.2.12` for releases, `v0.2.12.3` for dev builds) and links to the changelog page.
+- Editor: Find & Replace gained a **Current chapter only** option. When checked, search/replace runs against the open chapter instead of every chapter in the book; it stays unchecked by default, so the existing all-chapters behaviour is unchanged.
