/* ── Legal multilevel list — auto-numbering via CSS counters ──────────────
   The model emits clause structure as nested <ol class="legal">. Numbers are
   computed from the list position, not stored as characters — so when the
   lawyer adds, removes, or reorders clauses, every number renumbers
   automatically and stays consistent with cross-references at render time.

   Hierarchy follows Cyprus/English legal drafting conventions:
     Level 1: 1.        bold (clauses)
     Level 2: 1.1       (sub-clauses)
     Level 3: 1.1.1     (sub-sub-clauses)
     Level 4: (a)       lower-alpha
     Level 5: (i)       lower-roman
