# Single source of truth for Amethyst release asset naming.
#
# Two product lines share this contract:
#   amethyst-desktop-<version>-<family>-<arch>.<ext>   (Compose Desktop app)
#   amy-<version>-<family>-<arch>.<ext>                (Amy CLI — cli/ module)
#
#   <version> = tag stripped of leading 'v' (e.g. "1.08.0")
#   <family>  = macos | windows | linux
#   <arch>    = x64 | arm64
#   <ext>     = dmg | msi | zip | deb | rpm | AppImage | tar.gz
#
# Consumed by: .github/workflows/create-release.yml, .github/workflows/bump-*.yml,
#              BUILDING.md, local release runbooks.
#
# Usage:
#   source scripts/asset-name.sh
#   collect_assets     <family> <arch> <version> <dest_dir>   # desktop
#   collect_cli_assets <family> <arch> <version> <dest_dir>   # amy CLI
#
# Expected examples:
#   amethyst-desktop-1.08.0-macos-x64.dmg
#   amethyst-desktop-1.08.0-macos-arm64.dmg
#   amethyst-desktop-1.08.0-windows-x64.msi
