# Writers Guild Docker Image
#
# The image mirrors the repository layout (/app/server, /app/shared,
# /app/defaults) so every path the code resolves relative to its own file —
# shared/ imports, the defaults/ character cards — lands where it does in a
# checkout.
#
# Debian slim (glibc) rather than alpine (musl), so better-sqlite3 and sharp
# install from their published linux-x64 / linux-arm64 prebuilds instead of
# compiling from source, which is glacial under QEMU when the arm64 image is
# built on an amd64 runner.
#
# Track the current LTS line explicitly (24) rather than the `lts` tag, so the
# Node major only moves when we move it. The digest is refreshed by dependabot;
# see .github/dependabot.yml.
