A new element kind, sticker, draws layered vector illustrations from a library in twelve themes, behind its own entry point @trek/shared/stickers. Studio gets a Stickers rail section (themes, localized search, recently used, click or drag to place) and an inspector for colour slots, mirroring, turning and opacity. The assistant gets list_book_assets, add and style of stickers in edit_book_page, stickers in describe_book_page and an overlap warning for a sticker over words. BOOK_SCHEMA_REV goes to 2.
Changes held in one step are applied in the order the chat shows them, so
"undo all" walks them back newest first. A page put back is checked against
the digest of the page as the change left it, so a save to another page no
longer blocks the undo; restore_book_page takes these digests as an option and
keeps the whole book check without them. The book card counts the user's own
photos, the preview tool describes itself per role, a copy into another trip
names no places, a held vacay toggle says up front whether it can be taken
back, and a viewer's Studio prompt names none of the design's tools.
The page image test uploads through the real renders route after the real
privacy acknowledgement, for Anthropic, OpenAI, Gemini and the ChatGPT plan,
and keeps OpenRouter and an unacknowledged model to words. The book design
test drives design_book and a held apply_book_design through approval and
undo, with outsiders, editors of another thread and viewers refused.
