Languages landed but the voices did not: kokoro reported none until something
loaded it, so a client could see nine languages and still have nothing to pick
from. The names are now read out of the voices file the backend itself selects
from — the same file, so the listing cannot offer a voice that synthesis would
then reject — and the accent map already in the module decodes each one's
language and gender. 54 voices across all nine languages.

Pointedly NOT via _resolve_kokoro_files: that downloads a 28 MB release when
nothing local matches, and /v1/models is a polled endpoint, so it must never be
a download trigger. A file that is not on disk simply yields no names, and there
is a test that fails if the listing path reaches for the network at all. The zip
index read is memoised against the file's own mtime (27ms -> 0.1ms).

A list a load actually enumerated still outranks the file, and a card's
voices_path is honoured. XTTS keeps filling in after its first load, and parler
stays empty with selection "described" — it has no speaker names to give.
