/* UNICOSOFT external stylesheet.
 *
 * Hosts the shared "chrome" rules (reset, color variables, typography,
 * navbar, burger menu, mobile nav overlay, container, section, footer)
 * plus the Metropolis @font-face declarations. Every content page
 * links to this file, so these rules are parsed and cached once
 * across the whole site instead of duplicated inline per page.
 *
 * Page-specific rules (hero backgrounds, section layouts, forms, job
 * cards, team grids, etc.) stay inline in each HTML file. The
 * responsive @media blocks also stay inline for now — they are
 * internally mixed (chrome + page-specific) and splitting them would
 * require a separate pass.
