[0.6.6] - 2026-07-19

Fixed

• Facing pages meet cleanly at the spine. Each page of a spread now
  edge-aligns toward the center instead of centering in its own half, the 2px
  seam between the two views is gone, and the page-fit measurement no longer
  loses the width of the pre-fit scrollbar — which had left a theme-colored
  strip at the spine.
• Page turns can no longer leave pages unscaled. Navigating quickly could
  occasionally skip the reader-script injection, showing the raw page at
  natural size with scrollbars. The injected-script collections are now only
  rewritten when their content actually changes, and every finished load
  verifies the fixed-layout fit, re-injecting the script if it never ran.
• Backward navigation keeps the established spread pairing. Spread pairs
  are anchored at the front of the book, so stepping back from a lone final
  page rejoins the canonical pairs instead of shifting every spread by one.
• Arrow keys follow the reading direction on fixed-layout pages. In
  right-bound books ← advances and → goes back, matching the edge-click
  mapping.
