🏗️🔧：let the minified script say so in its name

The stylesheet is built on the rule that `.min` is a claim about what
is inside a file, so only the build that minifies makes one. The script
was minified under the name it arrived with, which says the opposite of
what had happened to it.

It is `count.min.js` now, and the unminified copy does not go out
beside it. The tag asking for it sits inside the block that only
renders for production, so it names the minified file outright rather
than deciding again in a condition that cannot be false.
