  from tarballs against the GNOME 46 runtime, then the app from the v1.0.0 tag
- Icon: app-id-named PNGs (128/512) for flatpak export, svg kept for native
  installs; desktop file Icon updated

- Version `1.0.0` is stamped in FOUR places: `meson.build`, `flake.nix`, `default.nix`, and the `<releases>` entry in `resources/io.github.bemagri.nomines.metainfo.xml`. Bump all four together.
- Release sanity: `nix build .` (validates the flake), `desktop-file-validate` + `appstreamcli validate --no-net` on the resources (wired up as meson tests).
- The metainfo screenshot URL points at `raw.githubusercontent.com/bemagri/nomines/main/...` — it 404s until the repo is published; replace if the repo moves.
- Flatpak: `io.github.bemagri.nomines.yml` builds libsigc++/glibmm/cairomm/pangomm/gtkmm from tarballs against the GNOME 46 runtime (matches the gtkmm 4.14/glib 2.80 stack we develop against), then the app from the `v1.0.0` git tag. The pinned `commit:` must match the pushed tag. The leaderboard needs the `--filesystem=xdg-config/nomines:create` finish-arg — don't drop it. Local builds land in `.flatpak-builder/` (gitignored); `flatpak-builder --user --install --force-clean build-flatpak io.github.bemagri.nomines.yml`.
- Flatpak module version traps (all verified by building): gtkmm 4.14 needs pangomm >= 2.50 (which still installs `pangomm-2.48.pc`; 2.48.x is too old), and cairomm tarballs live on `cairographics.org/releases`, not download.gnome.org. `appstream-compose: false` is set in the manifest because flatpak-builder's compose fetches the (still-404) metainfo screenshot URL — remove it once the repo is public. Flatpak's icon validation can't decode SVGs, so PNG icons (128/512) are installed under the app-id name and the svg is cleanup-removed; keep that convention.
