/* ============================================================================
   editor-components.css: styles for components added with the online editor
   ----------------------------------------------------------------------------
   The online editor links this file from a lesson the first time content is
   added, moved or rearranged in it. Most rules use :where() so that they have
   no specificity, and a lesson's own styles take precedence. The callout
   colours, R code and slide parts carry a little more weight, as noted below.
