The DMG opened as a plain Finder window. It now shows the app icon's figure on
the EffectCraft colour, with EffectCraft.app and the Applications link side by
side.
- packaging/macos/dmg/: background.svg (source; text outlined, the figure an
<image> of assets/app-icon) and dmg-layout.DS_Store (Finder view settings:
window, icon size 128, positions, background), written by generate.py on any
OS, byte-for-byte reproducible, with nothing from the machine that ran it.
- package.sh renders the SVG with resvg (1x + 2x) into a HiDPI TIFF at package
time, so no bitmap is committed; release.yml installs resvg 0.48.1 (pinned,
--locked) on the macOS runner. The image is still built with hdiutil
makehybrid.
- The volume name drops the version: the layout finds the background through
an alias that includes the volume name. The DMG file name keeps the version.
