Two changes so an English-speaking base never sees a blank name or native script:
- Filename romaji fallback: a blank-artist CDLC pack ("Artist_Title_v1_p") shows
nothing useful (artist blank; title = the raw filename), and a match fills it
with kanji/kana. query_page + pack_fields now surface the author's own romaji
parsed from the filename ("Junko Yagami — BAY CITY") when the pack has no
artist of its own — display-only, keyset-safe (raw title stashed for the
cursor), a real pack artist or a user override still wins.
- Smart adopt: "Use these values" now KEEPS the readable romaji name + title the
card already shows and takes only album/year/genre (+ art via the pin) from the
match, so identifying a Japanese song gives "Junko Yagami — BAY CITY — FULL MOON"
with the right cover, never native script.
Tests: romaji fallback fires for a blank-artist CDLC pack (grid + pack_fields
agree) and is left alone when the pack has a real artist.
