 * Loaded after main.css/table.css so these tokens and section-level
 * overrides win by source order without editing main.css's original
 * selectors directly.
 *
 * Note: base.css/main.css set the page's root font-size to 10px, so
 * every `rem` value in main.css assumes 1rem = 10px. The tokens below
 * use px/clamp() instead of rem to avoid silently inheriting that
 * unrelated convention in the new components this file styles.
