/* =========================================================================
   False Memory and Source Monitoring — tool-specific styling
   -------------------------------------------------------------------------
   Shared page furniture comes from components/tool-kit.css. What is specific
   here is the study card (which carries a source label as well as a word),
   the test panel and the item-type chart.

   HOW THE TWO SOURCES ARE DISTINGUISHED
   -------------------------------------
   By their NAME, printed in full above every studied word, and by a border
   style: the handout has a solid left rule, the whiteboard a dashed one.
   Never by hue alone. That matters twice over here - once for accessibility,
   and once because the whole point of the task is that source information is
   carried by the qualities of the experience.

   PRESENTATION SAFETY
   -------------------
   The study card changes once every 1.5 to 3 seconds and only its contents
   change; the card, its size and its position stay put. The test phase is not
   timed at all. No CSS animation or transition is used anywhere in this file.
