Understar CC0 Sound Effects Curated by NextGenRunGames from the Understar project's approved Freesound manifest. 300 individual sounds are included. Each item remains under its creator's own CC0 1.0 dedication; this collection does not extend the license to other Understar files or to the game. Every file's creator, original Freesound page, declared CC0 license, source-preview note, transformed-file SHA-256 and byte size are recorded in SOURCES.json. Audio is an OGG copy prepared from the Freesound HQ MP3 preview; it is not a lossless original. Some clips were trimmed and level-adjusted for the game. The project manifest preserves its measured source/processed details. CC0 1.0 deed: https://creativecommons.org/publicdomain/zero/1.0/
