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.

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.
