/* ══════════════════════════════════════════════════════════════
   Portfolio Monitor — showcase site

   Shares its design system with the report email (src/emailer.py):
   cool paper rather than cream, a humanist serif for voice, the system
   sans for utility text, and a monospace reserved for figures. The
   stacked thick/thin rule is the masthead device carried across both.
