/* ==========================================================================
   Road2Job - Premium Portfolio system, shared by the student portfolio
   (/u/{username}) and the institute portfolio (/institutes/{id}). Kept out
   of marketing.css since this is a large, page-specific system. Built
   entirely from marketing.css/app.css tokens (--r2j-*) so it matches the
   rest of the site in both themes rather than inventing a new palette.
   Loaded only on portfolio-style pages via the layout's $extraStyles.
