/*
 * Shared site header for the web portal: Dashboard, MCP Console, Setup Guide and Developer Notes.
 *
 * The header markup is the same on every page, so its style lives here, once. It is deliberately self-contained (own colours,
 * own font stack) because the pages name their CSS variables differently (--text-muted vs --muted, --cyfirma-red vs --bad) and
 * the Console uses a different body font. Page-local copies of these rules are what made the four headers drift apart: different
 * widths, different wrapping, different gaps and logo sizes. Change the header here and nowhere else.
 *
 * --shell-max is the one page width for all four pages, so the logo and the content start at the same x on every page.
