/* ==========================================================================
   Assessment — the overview dashboard, the skill radar and the wizard
   --------------------------------------------------------------------------
   Composed entirely from the tokens in base.css. Two rules drive the layout:

   * A case diagram is *sized by its container*. `case_thumbnail()` emits a
     viewBox-only SVG so it can be drawn crisply at any size — which also means
     an unstyled one expands to fill whatever box it lands in. Every diagram on
     these pages therefore goes through `.case-diagram` with an explicit size
     modifier.
   * The wizard is one step per screen. Rating 119 cases is a rhythm, and the
     rhythm breaks the moment the student has to scroll to find the buttons.
   ========================================================================== */
