The fixed Explorer header provides Back for any selected sealed series, product type or search, in both Pokemon and One Piece. Foudre Noire is the reported example, not a hardcoded special case. Returning clears active filters while retaining the game, grouping and expanded blocks. Root profile and pushed-screen stack actions are preserved.

Separate failing tests reproduced missing series and type back actions before implementation. Seven behavioral assertions now cover both games, series/block restoration, type reset, search reset and root/pushed behavior. Legacy Explorer source-expression coverage was replaced by direct behavioral assertions. Lint and typecheck passed; full suite: 2498 passed, 11 skipped. No native, backend or dependency changes; no device E2E/iOS build claimed.
