Formula Trace
Auto Layout width = sum(children widths) + padding + spacing
Step 1: Children widths = 100 + 150
Step 2: Padding = 20 (left + right)
Step 3: Spacing between children = 10
Step 4: Auto Layout width = 250 + 20 + 10

3 |Button with Auto Layout |Flexible   |Resizes with content
4 |Container |300        |Fixed width
5 |Container with Auto Layout|Flexible |Resizes with children

Arrows: Auto Layout width depends on children widths (B2, B3), padding, and spacing.
Cells B2 and B3 represent children widths feeding into Auto Layout width calculation.

4 |Container |300        |Fixed width
5 |Container with Auto Layout|280      |Resizes with children

Cell B5 shows Auto Layout container width calculated as 280px.
The Auto Layout container width (B5) adjusts to 280px based on children widths, padding, and spacing, showing responsiveness.
