/**
 * SPF Generator & Analyser — tool styles
 *
 * Layout, the record readout, and the two list shapes the analyser needs.
 * Cards, buttons, alerts, badges, chips, tabs and stat tiles all come from
 * frikwork and the app layer; nothing here restyles one of those.
 *
 * v1's stylesheet also restyled `.nav-pills` and bare `code` globally, which
 * leaked into every other page that happened to load it. Everything below is
 * behind an `spf-` prefix.
