Tricky words can't be sounded out — they're learned by meeting them often. A flashcard session is one way; a bookmark that lives inside the reading book is the sneakier one, because the list is there every single time the book opens. Pick the phase, print five identical bookmarks per page (landscape), cut, done. No signup, nothing uploaded.
Print landscape on card if you can (paper works fine glued to cereal box). One for the book bag, one for the bedside book, spares for the inevitable. Lowercase throughout, as schools teach. The same phase lists power our flashcard generator — cards for practice sessions, bookmarks for ambient exposure.
