- New solitaire_assetgen crate with gen_sfx binary: synthesizes five 44.1kHz mono 16-bit PCM WAVs (flip/place/deal/invalid/fanfare) from an LCG noise source + sine/square synths. Output committed under assets/audio/. - AudioPlugin (engine): embeds the WAVs via include_bytes!, decodes once with kira::StaticSoundData, plays on Draw / Move / NewGame / GameWon events. card_invalid is loaded but unused — wiring it needs a MoveRejectedEvent. - AudioManager kept on the main thread (NonSend) since cpal is !Send on some platforms; degrades gracefully if no audio device present.
