          Native Linux x86-64 packages. Installation and removal are handled by your distro package manager; `setup.sh` and `uninstall.sh` are no longer required.

          ### Install

          **Debian / Ubuntu / Linux Mint**

          \`\`\`bash
          sudo apt install ./flstudiorpc_${VERSION}_amd64.deb

          **Fedora / RHEL-family**

          \`\`\`bash
          sudo dnf install ./flstudiorpc-${VERSION}-1.x86_64.rpm
          \`\`\`

          **Arch Linux / CachyOS / EndeavourOS**

          \`\`\`bash

          sudo pacman -Rns flstudiorpc
          \`\`\`

          The package manager owns and removes the executable, application-menu entry, installed icons, and license file. Per-user preferences under \`~/.config\` are intentionally preserved.
