The audiophile preset (fallback_enabled=False) still shipped a "FLAC 16-bit"
target in its ladder, so 16-bit FLAC matched and imported even though the name
implies hi-res-only. Split the ladder: audiophile now uses a strict 24-bit FLAC
list; balanced keeps 24-bit + 16-bit + MP3. Gives users a one-click strict
"24-bit only" profile that actually rejects 16-bit/lossy.
Not a matches_target bug — that correctly rejects 16-bit vs a 24-bit target;
the leak was the preset's target LIST including 16-bit (+ fallback accepting
off-list lossy like MP3-128).
