   DESIGN & NAVAL ARCHITECTURE — page-specific styles (design-engineering.css)
   Global rules (reset, colors, fonts, .container, .btn, .card, .hero,
   .section, .section-head, .grid, navbar, footer) live in /style.css.
   Colors/fonts come only from the §6/§7 variables — no new colors;
   --dusty-denim is the only accent.
