[0.9.0] - 2026-09-30

Added

• Color handling choice for themes, in View ▸ Theme:
  • Prioritize Readability (Auto-Correct Colors) — the default. Text takes
    the theme color as before, but where the book paints its own background
    (a black heading band, a grey column box) the text is switched to black or
    white so it keeps at least a 4.5:1 contrast on it. Previously such text
    could end up dark on dark and unreadable.
  • Use Book Colors — the theme only supplies the page background and the
    default text color; any text/background colors the book specifies are kept
    as a matched pair.
• File ▸ Save Page… (Ctrl+S). The reading view's context-menu "Save page"
  is now also available from the File menu.
