# Usage:
#   ./build-and-push.sh <registry/image:tag>
#
# Example:
#   ./build-and-push.sh ghcr.io/yourorg/plano-redis:latest
#   ./build-and-push.sh docker.io/youruser/plano-redis:0.4.17
#
# The build context is the repository root. Run this script from anywhere —
# it resolves the repo root automatically.
