+RHEL packages are built on Rocky Linux base images. The build scripts detect
+`OS=rhel` from `/etc/redhat-release` (which reports `Rocky Linux release ...`),
+so the produced `.rpm`s are ordinary Red Hat / rpm packages. AlmaLinux is _not_
+recognized by `build-scripts/detect-environment`, which is why Rocky is used.

-Adding a non-debian based platform (e.g.,
-RHEL/CentOS) requires a new `container/Dockerfile.rhel` plus platform entries.
+Adding another RHEL-family platform (a new Rocky/RHEL major version) works the
+same way: add a `platforms.json` entry with `"dockerfile": "Dockerfile.rhel"`
+and a matrix entry, then set any per-version `extra_build_args` — `CRB_REPO`
+(`powertools` on 8, `crb` on 9+), `PHP_MODULE_STREAM` (`remi-8.3` where the
+distro's default PHP is older than 8.3; RHEL 10 already ships 8.3), and
+`EXTRA_PKGS` for version-specific packages. Note that `--update-sha` also works
+for the namespaced `rockylinux/rockylinux` base images, not just official
+Docker Hub library images.
+
+Adding an entirely different, non-RHEL/non-Debian platform family (e.g. SUSE)
+would require a new `container/Dockerfile.<family>` plus platform entries.
