/* ── Water filtration division (2026-09-13) ───────────────────────────────
   Four components the other divisions never needed, because this division
   argues from published utility data rather than from job experience:

   .verdict   the plain answer to a question the market gets wrong, set apart
              so a skimmer and an answer engine both find it first
   .datatable a sourced figures table — every row carries its source link, the
              same contract the /costs/ pages use
   .spec      a two-column definition list for system specifications
   .steps     the ordered install/treatment sequence, where order is the point

   Deliberately NOT reusing .faq: a structural checker counts .faq blocks
   against the FAQPage schema, and borrowing the class would report a count
   mismatch on every page here. Same lesson as .localfact above. */
