/*
 * Shared styling for the long-form pages: the case studies and the
 * definitional guides.
 *
 * The older article pages (sales-director, the six blog posts) inline these
 * same rules in a <style> block. That was fine for a handful of pages, but the
 * site now has enough of them that duplicating ~6KB of identical CSS into every
 * file costs more than one cached request. /assets/* already carries a long
 * edge TTL in netlify.toml, so this is fetched once and reused site-wide.
 *
 * Visual output is deliberately identical to the inlined version, so a reader
 * cannot tell which generation of page they are on.
