#!/usr/bin/env bash
# Test runner for the theme-studio tool. Drives the whole pyramid in one command:
# - regenerate theme-studio.html from generate.py
# - Python templating tests (export-strip + placeholder substitution)
# - Node unit tests for colormath.js (+ inline-integrity)
# - syntax-check the spliced page <script>
# - browser hash gates in headless Chrome (#selftest and the metric tests)
#
# Exit status is non-zero if any stage fails. Browser gates need a Chromium-family
# browser; when none is found they are reported as SKIPPED (not passed) so the
# gap is visible rather than silently green.
#
# Usage: scripts/theme-studio/run-tests.sh (or: make theme-studio-test)
