# Shared base image for all SnD Floaters tasks.
#
# Build from the repository root:
#
#   docker build -f snd-floaters/shared/Dockerfile \
#     -t ghcr.io/qrlow/snd-floaters-base:1.0.0 .
#
# The image contains only candidate-facing material. Answer keys, graders, and
# oracle files remain in each task's tests/ and solution/ directories.
