- Verified runtime improvement by comparing `scripts/highlight.php` on the `one-line.json` test case from D14273 with the new lexer enabled and commented out. Saw >10x local improvement. My local base runtime is also >10x better than the runtime from D14273. My laptop might be a little faster than whatever that hardware was, but this is probably mostly `pygmentize` improvements in my most recent version.
- Added a test case.
- Used the highlighter to produce reasonable-looking results:
