The public dictionary needs no login

My wordbook stays in the folded tool
Saves and review live in Search. Guests start at login.
Lemma pages stay a dictionary
Do not put a marketing banner on word URLs. The title is the lemma.
READ FIRST
The open wordbook is a dictionary. People should read senses and lists without an account. The page Googlebot sees is the page a guest sees. Your cards are a different layer. Saved words collect in the Search wordbook, and only that layer needs login. Do not mix looking up a word with reviewing your list on one folded surface. A lemma URL is that word’s landing. Repeating the same banner on thousands of URLs pushes the definition down. Fold the lists. Leave the word page a dictionary.
