 * The page is a search that answers in public: an ink asking-band at the top,
 * then ten cards on paper. Each card owns an accent colour, and the colour of
 * whichever card the search likes best leaks into the band above it, so the
 * page visibly changes its mind as you type.
 *
 * Nothing here belongs in site.css — a second page must never inherit the
 * asking-band by accident.
