/* Etude — the guide pages' demos: small crops of the app, played by
 * assets/vignette.js. Each stage is laid out at its own size (data-w ×
 * data-h on the figure) in the app's own points, and scaled to the column
 * (up to data-max), like the front page's demo.
 *
 * Sizes and colours follow Etude 0.2.0's theme (MagpieUI/SettledTheme.json
 * and Theme.swift: 13 pt body, 12 pt labels, 11 pt captions, 16 pt glass
 * corners, 12 pt cards); the window and bubble colours are the ones measured
 * on screen for the front-page demo (assets/demo.css). Icons are in
 * assets/vg-icons.svg. */
