Responsive Example

This example shows breakpoint layers and how they resolve through Responsive::at_breakpoint(...).

• File: examples/04_responsive.rs
• Run:

& "$env:USERPROFILE\.cargo\bin\cargo.exe" run --example responsive

• Expected output: one line per breakpoint showing the resolved width, height, padding, and shadow values.

Why this exists: responsive behavior should be inspectable without launching a GUI backend.
