• Desktop (Windows, macOS, Linux) — via Tauri, lightweight native binaries under 10MB
• Steam — Tauri build, packaged with Steamworks SDK
• Discord Activities — runs inside Discord via their Embedded App SDK
• WeChat Mini Games — export with platform-specific adapter
• Web portals (CrazyGames, Poki, Newgrounds) — integrate their SDK for ads, leaderboards, and distribution

Same codebase. Different packaging.
