# ── Timmy Time — Test Runner Image ───────────────────────────────────────────
#
# Lean image with test dependencies baked in.  Designed to be used with
# docker-compose.test.yml which bind-mounts src/, tests/, and static/
# so you never rebuild for code changes — only when deps change.
#
# Build:  docker compose -f docker-compose.test.yml build
# Run:    docker compose -f docker-compose.test.yml run --rm test
#
# The builder stage is shared with the production Dockerfile so
# dependency layers stay cached across dev ↔ test ↔ prod builds.

# ── Stage 1: Builder — export deps via Poetry, install via pip ──────────────
