  /* Fixed to fit exactly 1 header row + the max 10 ranked records
     (see lib/hallOfFame.js TOP_N=10) so the popup never grows or
     shrinks depending on how many records a section actually has —
     it's always sized as if it were full. Row height below is
     pinned with an explicit line-height (not just padding), since
     the CSS `height` on a table cell is only a floor — the browser
     still grows a row past it to fit the default line-height.
     11 rows x 2.2rem + a small buffer for border-collapse rounding.
     overflow-y:auto stays on only as a safety net; it should never
     actually need to scroll. */
