  Visual language: "la vitrina de elementos" from the app's DESIGN.md.
  Real screenshots of the app, element cells on white with their family
  color as a bottom bar, and the Lavoisier teal accent. Light theme only. One solid accent from the app icon for links and focus.
  System font on purpose: it is the app's own voice on Apple devices and
  keeps the page free of third-party requests.
