/* -------- Data table (dense, wide) --------
   Used by features/templates/example-data-table.html.
   For large datasets (thousands of rows): smaller text, tighter
   padding, and a page that widens beyond the normal .site-main column
   so more columns fit. Rows wrap instead of forcing a horizontal
   scrollbar — a bottom scrollbar on a data table reads as "the page
   is broken", not "scroll to see more" — and pagination (below) keeps
   the number of <tr> elements on screen at once manageable so the
   page itself doesn't get unreasonably long. The header row uses
   position: sticky so it stays visible while scrolling; --header-height
   is measured from the real .site-header by syncHeaderHeightVar() in
   /js/main.js so it lines up under the sticky site header rather than
   being hidden behind it. */
