/* Module components — step 2 (revised for originality). Built against

   Signature devices unique to this system, replacing the reference's
   own vocabulary rather than reskinning it:
   - a fleuron mark (--mark-fleuron) opens every header bar, in place of
     a plain bullet/icon
   - a dotted leader rule (a table-of-contents idiom) runs between a
     label and its value, in header bars and link rows alike
   - list rows are auto-numbered via CSS counters, not manually marked up */
