Module capstone: full responsive layout

Theory
Putting B2 together
Build a complete page layout using ONLY flexbox. The page has:
- A header with logo (left) and login link (right).
- A main content area that's a sidebar + main split.
- A footer with 3 navigation columns side-by-side.
Each section uses a different flex pattern from this module:
- Header —
justify-content: space-between(lesson 5). - Layout — fixed sidebar + flex: 1 main (lesson 9).
- Card row in main — flex-wrap + gap (lessons 7-8).
- Footer — three equal columns with flex: 1 each.
This is the kind of layout every SaaS dashboard ships. After you can build this from scratch, flexbox is muscle memory.
