/* === MOBILE TABLE FIX (audit 2026-05-06h) ==============================
   Earlier `word-break: break-word !important` on table cells was splitting
   numbers character-by-character ("1836.15267" rendering as "1836 / .1 /
   52 / 67"; "MEASURED" wrapping vertically). Reverse that: keep horizontal
   scroll inside .table-wrap and let cells stay ONE LINE per value.
   Also fix display equations that push past the viewport.
