Unit 5: Assets, CSS, Responsive Design, and Accessibility

The portfolio finally gets a deliberate visual system in this Unit.

But we are not leaving systems thinking behind.

You will trace assets through Jekyll, separate generation from browser styling, build responsive CSS, and verify semantic/keyboard/image accessibility in the generated pages.

Unit question

How does source become a usable visual interface without hiding asset, browser, and accessibility failures behind "it looks fine on my screen"?

Upstream foundation

This Unit adapts Jekyll's official Assets/static-file behavior and source/build conventions. Robotnix adds the responsive-design and accessibility instruction around the generated site.
