/*
 * The phone addiction test (/tools/phone-addiction-test), ALE-221's second
 * free tool. Loaded after style.css.
 *
 * ⚠️ **It adds up the answers with CSS counters, and no script.** Each answer
 * is a radio whose `:checked` increments `total` by its own value and
 * `answered` by one; the line at the end prints both with counter(). So the
 * page keeps the site's policy with no script-src at all - unlike the timers,
 * which need one to ring. The line has to come after the ten questions in the
 * document: a counter is read where it is printed, in document order.
 *
 * Immutable in the Caddyfile, so a change here is test-2.css.
