# ensure-browser.sh — resolve (and if needed download) a headless Chromium for
# screenshots; prints the browser executable path to stdout. Reached via
# `maude design ensure-browser` (DDR-062), never a raw bin path.
#
# Usage:
#   ensure-browser.sh [--no-download] [--json] [--quiet]
#
# --no-download resolves an already-present browser only (never fetches ~94 MB) —
# use it from readiness probes. Default may download chrome-headless-shell into
# the Maude browsers cache (~/.maude/browsers, override MAUDE_BROWSERS_DIR).
# Exit 0 with the path on stdout when a browser is available; exit 1 otherwise.
