/* The horizontal scroller for wide tables.
 *
 * The overflow used to sit on the `<table>` itself, with `display: block` to
 * make it a scroll box. That was wrong twice: `display: block` on a table
 * drops the table semantics in several browsers, and a bare scroll container
 * cannot be reached by keyboard at all — WCAG 2.1.1 Keyboard, Level A. A
 * mouse user could drag the columns into view and a keyboard-only user simply
 * could not.
 *
 * So the table keeps `display: table` and tools/build_legal_pages.py wraps it
 * in `div.table-scroll[tabindex="0"][role="region"][aria-labelledby]`. That
 * generator carries the full reasoning, including why the name comes from the
 * heading above the table. Both halves are required; neither works alone.
 *
 * The focus ring is the one `:focus-visible` already draws for every element
 * on this site — 3px of --gold-deep. No new colour is introduced here on
 * purpose: --gold-deep #A8761A measures 3.70:1 on --parchment #FBF6EC and
 * 4.39:1 on --vesper #1C1726 (computed 2026-09-01), both clear of the 3:1
 * that 1.4.11 Non-text Contrast asks of a focus indicator, on both grounds.
