/* TableDI manual /docs/ — layout + components layered on /style.css.
   Only what style.css does not already provide: the two-column shell, the sidebar,
   the on-this-page box, the pager, chapter cards, and the pieces render.mjs emits
   (callout / figure / table wrapper / code block / kbd).
   Design tokens all come from style.css; the one it lacks (--soft) is defined here. */
