- packaging/macos/dmg/generate.py writes background.tiff and DS_Store on any OS (resvg with
the repo's fonts; ds_store and mac_alias, as dmgbuild uses). Both are byte-reproducible and
carry nothing from the machine that made them.
- DS_Store: same window, icon size, positions and background alias as before, without the
bookmark (pBBk/pBB0) and the alias's disk-image record, which held the author's boot volume
UUID and name, its creation date and temporary paths.
- background.tiff: the same pixels as before (checked), now opaque RGB with Deflate (1.8 MB to
1.0 MB) and LittleCMS's built-in sRGB profile instead of an HP profile with no open licence;
no file names or software tags.
- background.svg: drop an unused pattern and the xlink namespace (renders the same).
- ASSETS.md rows for the three files; README, docs/releasing.md (volume name) and ROADMAP.
