Improve demo content

[davestewart]

Background

The demo content started as both a technical showcase but also attempted to replicate "real" content by emulating a recipe site. However, as more example have been added to the demo, the "recipe" content seems out of place, and with certain features, gets in the way of communicating technical information.

Proposal

Ditch the recipe content:

• rename titles to what the page does
• remove recipe content
• add technical information where appropriate
• potentially change images (could use AI ones from a Facebook gallery for fun!?)
