-- Module:Compare — Phase 12 comparison-table renderer (Arms of God).
-- Reads Data:Compare_<Cat>.json (headers + rows of {t=display, s=sortval}).
-- Renders a class="sortable wikitable" with data-sort-value on numeric cells.
-- Pure presentation; no game logic. Re-run safe — data lives in the Data: page.
