# wmtiles build orchestration.
#
# The repo contains only source. Build artifacts (testdata fixtures, viewer
# bundle, library dist, CLI binary) are produced by these targets.
#
# Usage:
#   make             produce everything needed to run the CLI ($(BIN))
#   make test        run all tests (Go + Bun)
#   make typecheck   typecheck both TS packages
#   make clean       remove all generated artifacts
