"""quality_meets_profile / targets_from_profile — the shared strict
quality-decision core used by BOTH the import quality guard and the library
quality scanner. A file "meets" the profile iff its real measured quality
satisfies at least one ranked target (bit depth + sample rate are minimums;
fallback is NOT consulted — that's a download-time concession, not a definition
of quality).
