/*
 * /tools/name-checker — the checker and Name Inspector (content pipeline item 4).
 *
 * The visual job is one thing: make the NAME the subject of the page. A report about somebody's
 * name that opens with a table reads like a receipt, so the characters are set large at the top,
 * the surname is visibly a different thing from the given name, and each finding points back at
 * the character it is about. Everything under that is ordinary card layout.
 *
 * Effects are chrome, per the retention layer's rule: nothing here is clickable, nothing shifts
 * layout, nothing animates near an ad unit, and every animation is off under reduced motion — a
 * report that assembles itself is pleasant, and one a reader has to wait for is not, so the whole
 * sequence is under half a second.
 *
 * Dark mode goes through [data-bs-theme="dark"], as everywhere else on the site.
