          ## ${PLUGIN_NAME} v${PLUGIN_VERSION}

          Built on top of [rust-samp ${SDK_VERSION}](https://github.com/NullSablex/rust-samp/releases/tag/${SDK_VERSION}).

          ### Artifacts
          - \`${PLUGIN_NAME}.so\` — Linux i686 (\`i686-unknown-linux-gnu\`).
          - \`${PLUGIN_NAME}.dll\` — Windows i686 (\`i686-pc-windows-msvc\`).
          - \`${PLUGIN_NAME}.inc\` — Pawn include, identical file for SA-MP and Open Multiplayer.

          ### Compatibility
          The binaries are **universal**: they run on SA-MP and on Open Multiplayer, on Linux and Windows alike.

          - **SA-MP**: register under \`plugins=\` in \`server.cfg\`.
          - **Open Multiplayer (native mode, recommended)**: register as a component under \`components\` in \`config.json\`. Loaded via \`ComponentEntryPoint\`, with access to \`ICore\`, \`ITimersComponent\` and the remaining native APIs.
          - **Open Multiplayer (legacy mode)**: still supported — register under \`legacy_plugins\` (or the equivalent key in your \`config.json\`) if you prefer the SA-MP compat path over the native component. Same binary, no extra build flags.
