+## First: put calamares (and the other AUR rebuilds) into [tanin]
+`calamares` is AUR-only, so mkarchiso can't pull it from the official repos — it
+must live in `[tanin]`. Heavy Qt build (installs makedepends via sudo):
+```sh
+cd /tmp && rm -rf calamares && git clone https://aur.archlinux.org/calamares.git
+cd calamares && makepkg -sf --noconfirm
+cp ./*.pkg.tar.zst ~/projects/tanin-repo/
+# publish (create a write:package token in Gitea → Settings → Applications):
+TANIN_PKG_TOKEN=<token> ~/projects/taninux/packaging/publish-tanin-repo.sh
+```
+(If the AUR `calamares` lags a Qt bump, try `calamares-git`, or fall back to
+`archinstall` — already in the live base.)

 ## Build

 ./bootstrap-profile.sh          # assemble build-profile/ (releng base + overrides)
