Sources

Where an answer came from: Sources holds a turn's sources and numbers them once, Citation is a quiet numbered chip in the running text that opens its source and previews it in a hover card (the site, the title, the passage, when it was read), and SourceList lists them under the answer or as what a search call found. Resting on a citation lights its row, and resting on a row lights its citations. A source the model gives a url that is not http or https shows as text.
