   Project detail pages — shared overlay stylesheet.
   Loaded after main.css to bring detail pages into the new design system.
   Targets the existing class names (.project-content, .feature-section,
   .feature-list, .tech-item, .tech-stack, .status-section, etc.) so no
   markup restructure is needed.
