/* TQuest styles. Same chassis as TypeQuest: a sticky station rail (desktop) or a top bar (narrow), one reading column.
   Signature: story recaps and the student's rule cards render on ruled notebook paper ("sheet") in both themes, because the
   chapter is about what gets written down and retold. Accent is sunlight (O'Brien: "it's about sunlight"); the rule line is a notebook blue. */
