#
# The lexer's mistakes are invisible on a phone -- a line greyed out as a comment looks
# like a comment -- so this asks it directly and prints every span with the text under
# it. It is how the `/*`-pairing and URL-comment bugs in TRANSCRIPT_RENDERING.md were
# measured, and it is what any fix has to be checked against.
#
# Usage: ./highlights-repro.sh [LANGUAGE FILE]   (default: the known-bad cases)
