# run-tests.ps1 - regenerate tests/<slug>.html (one per component) + tests/index.html

# Test pages embed an iframe of the real H5 demo (frameworks/<Prefix>.html). Component CSS and the
# demo's inline script actually run inside that frame, and tests/_runtime.js runs every assertion
# against the frame document. Nothing is snapshot-copied here: copying body HTML while stripping
# <script> produced empty test pages, because all 79 demos render their DOM from inline JS.

# Output is UTF-8 WITHOUT BOM (PS5.1 `Set-Content -Encoding UTF8` would prepend a BOM).
# This script is intentionally ASCII-only: PS5.1 reads BOM-less files as ANSI, so any non-ASCII
# literal here would be mangled. Chinese labels live in the UTF-8 templates instead.
