Missable-achievement rules
Hidden interactions are missable inside their current task, but they do not require a full save reset: finish the story, select the relevant task in the Notebook, and replay that chapter. The checklist is stored only in your browser and does not alter Steam progress.
Verification notes
The complete asset atlas contains 50 images: 49 named achievement icons plus a generic Locked state. The page deliberately counts identifiable achievements rather than treating that reusable locked artwork as a separate unlock.
