/* PMI Business Systems: guides, answers and tools (wave 1, 2026-10-08).
   Loaded after pmi.css on /what-is/, /answers/ and /tools/ pages only.
   Uses the tokens and components already defined in pmi.css; adds only what a
   long-form page needs (breadcrumb, prose measure, tables, related list, calculator).
   Generated pages live in scripts/pmi_pages.py; this file is hand-edited. */
