/* Portfolio — custom styles on top of Bootstrap 5.3 (CDN).
   Goals:
   - Match the previous Tailwind + custom-keyframe visual 1:1.
   - Use the same color palette (Pantone "Space Sport") via CSS variables.
   - Provide the same animations (fade-up, fade-left, fade-right, progress,
     modal-in, hero slider, skill-bar fill, navbar hide-on-scroll).
