1) The document discusses prototyping workflows in Sketch and how they are transitioned to the web in Sketch Cloud. This posed challenges around fluently transitioning between screens. 2) A solution involved preloading relations between artboards recursively using recursive common table expressions (RCTE) in MariaDB to query for all related artboards with one query. 3) The document explains how RCTEs work and provides an example implementation for querying related artboards in Elixir/Ecto using fragments until native RCTE support is added to Ecto. This allows composable queries to retrieve all related artboard structures.
