/*****************************************************
EDITORIAL DEMO

A landing-page opening with a real Xanthan passage and its editable source
side by side. Three views show a figure, a pull quote, and a contextual note.
The introduction pairs a serif headline, a lead, and optional illustration on
the page surface; the demonstration has a contrasting band.

Loads:    every page
Used by:  layout/editorial-demo.html
Needs:    base.css tokens and container grid, home.css --home-measure,
          images.css and typography.css for the actual sample components
Not here: ordinary figures and pull quotes (images.css, typography.css), or
          the image-backed landing-page hero (home.css)
