/* U plan site shell styles, contract v1 (spec 8.6 and 8.9).
   Only the parts that 8.9 gives to the shell: article body after the lead,
   sources, feed, end of feed, footer, the reward entry and panel, info,
   language and not-found pages. Colours come only from the contract
   variables (light and dark sets are defined once, in CONTRACT_CSS);
   logical properties keep right-to-left pages correct. */
