Find synonyms for a tag and add the good ones to the vocabulary as new tags.
Pick an existing tag from the dropdown, or type a free term.
corpus finds look-alikes among the thousands of tags already applied to releases; LLM asks a
model for synonyms / variants (the slow part — a spinner shows elapsed time).
Each candidate is marked canonical (already a tag) or new. Check the new ones you want and
add them as new tags. Nothing is pre-checked.
