 *   2. Everything else takes the colour of its section band in the global nav,
 *      so a card on the landing page and its group in the left rail agree.
 *
 * An accent names a section, not a rank, and it goes on the header, never on
 * `.catalog-card` itself. Do not pick one for variety: every card in a section
 * takes the same accent. Adding a colour here means adding a section to the
 * nav, not giving one guide a look of its own.
