/* =============================================================
   portfoglio — Bruno Matos
   Vanilla CSS, no framework, no external requests.

   Palette and type are the main site's (ai/assets/css/rettro.css):
   same purples, same pixel chrome — hard offset shadows, square
   corners, monospace throughout — so the portfolio reads as part
   of brunomatos.pt rather than a bought theme.

   The two families are NOT fetched from a CDN here: this folder is
   standalone and must render on its own. VT323/JetBrains Mono are
   named first and degrade to the system monospace stack, which is
   the same shape and costs nothing.

   Mobile-first. Light and dark both ship.
