# e2e.Dockerfile — Run E2E tests in CI-like Linux environment with resource limits
#
# Usage:
#   make test-e2e-ci                                    # All tests
#   make test-e2e-ci E2E_ARGS="--shard=1/4"            # Single shard
#   make test-e2e-ci E2E_ARGS="tests/diff-update.spec.ts"  # Specific test
#   make test-e2e-ci E2E_CI_CPUS=2 E2E_CI_MEMORY=4g   # Custom limits
#
# Note: Builds for native architecture (ARM64 on Apple Silicon). To match CI
# exactly (x86_64), add --platform=linux/amd64, but expect ~10x slower builds
# due to QEMU emulation. The default is fine for reproducing timing/resource issues.
