docs/handoff/godot-ci-custom-image.md was the original handoff spec for this
repo's creation, already marked "done, and superseded" — it describes the
barichello/godot-ci-based Dockerfile this repo has since moved off of (see
wayfinder map #2, ticket #7). No longer a useful reference now that the
current README and Dockerfile are the source of truth.

Answers wayfinder ticket #8: does a glibc-based slim distro
(debian:bookworm-slim / trixie-slim) get most of Alpine's size win
without the musl risk #4-#6 found?
Verdict: not worth it. Debian bookworm-slim (26.92 MB compressed) is
within ~5% of ubuntu:noble (28.37 MB) per Docker Hub's official image
listings - nowhere near Alpine's musl size class. Debian does clear
every capability gap Alpine hit (posix-threads mingw-w64 in stable,
X11/audio dev headers, official Blender tarball runs unmodified since
it's glibc), but the size case for leaving Ubuntu was Alpine's alone.
Related to #4, #5, #6
Answers wayfinder issue #6: Alpine's community/edge repo ships a
posix-threads-only mingw-w64-gcc cross toolchain, but it's edge-only
(not in a stable release) and no primary source confirms anyone has
built Godot Windows export templates with it.
Related to #6
Captures findings for wayfinder ticket #4: whether official Godot
Linux editor/export-template binaries run under Alpine/musl.
Throwaway research branch, not intended to merge.

Verdict: official glibc tarball does not run on Alpine as-is; gcompat
is not a credible fix for something Blender-sized (per gcompat's own
docs and one concrete failed community attempt). A musl-native
alternative exists (Alpine community's blender-headless package,
5.2.0-r0) but only on the edge branch, not a stable release — a real
argument against Alpine for this pipeline's pinned-version needs.

Replace the fixed 4.7.1 Dockerfile/workflow pin with:
- a nightly schedule that resolves the newest stable Godot (4.0+) and
newest stable Blender, and builds+pushes <version> plus a floating
latest tag only when the Godot version actually changed
- a workflow_dispatch free-text version input to (re)build any specific
Godot version on demand, always with newest-at-build-time Blender,
overwriting that tag without touching latest
- scripts/resolve-godot-version.sh and scripts/resolve-blender-url.sh,
with shared parsing logic in scripts/lib.sh and an offline smoke test
in scripts/test-lib.sh
- Blender is now fetched directly from download.blender.org instead of
apt (Ubuntu noble's apt package is stuck on 4.0.2)
- drop the push-to-main trigger; schedule + workflow_dispatch only
Scope is Godot 4.0+ only — .blend import is a Godot 4 feature, so 3.x
builds have no use for the Blender toolchain this image adds.
