| # Manual-dispatch verification of the "opens in Inkscape" claim in README.md. | |
| # | |
| # Not in the per-PR path because Inkscape + GTK deps is ~300 MB and cold start | |
| # is ~2 s per file. librsvg (in ci.yml) catches the same classes of failure at | |
| # a fraction of the cost — this workflow exists to verify the specific marketing | |
| # claim before a release, and to produce a PNG gallery a human can eyeball. | |
