Anti-Spoiler in booklet (not single) may shift doubles

[yonixw]

🐜 Describe the bug

Since we add 1 Page side we may shift the double page until next anti spoiler

We should think about this instead:

• On the first page use anti spoiler if no cover
• In the middle, Add a full page? might be in the middle of double (on up and/or down flows)
  • But I think we can always add a page in-between booklet page flip (which might be +- 1 from asked batch count)
• In the end, need to be careful... can add only if not in the middle of double other wise need to do some movement
  • See end-transform below, ... maybe do it to booklet end always ?
  • Maybe even if no double? "Chapter Make Even" might break doubles too.. need to check

End Transform, from:

// RTL, Last Page
Z , X
M2, M1 (Might be double)

// Need to add extra face (because we add face for cover at the start)

To:

Z, X
A, M1

A, M2
A, A

A, A

Where A=AntiSpoiler but might be E=MakeEven

• Allow Page 1/3 for anti spoiler, makeven? (kinda extra metadata?)

📝 Additional context

Build Version: v2.6

No need for rotating transform after adding 2 faces/4 sides for anti spoiler

But we have to make sure with 3d preview before closing this issue
