/* Critical Point Vision Site: pages.css
 * The parts that only exist because the site is six pages instead of one:
 * the compact page top on every inner page, the "more" link that sends a
 * home section to its fuller page, the single next block at the foot of an
 * inner page, and the cross-fade between pages. Loads on every page.
 * Tokens only. No new button styles.

   lead sits under it, and the first section starts straight after with no
   intro of its own (its intro is a part the home page alone requests). */
