/**
 * TWTIS Swipe — styles.
 *
 * Part 1: site chrome (logo + menu) is shown only at >= 1280px — the smallest
 *         "looks like" resolution of a 13-inch MacBook. Below that the site is
 *         the pure image feed.
 * Part 2: the fullscreen swipe overlay (mobile photo viewer), variant C:
 *         photo first, quiet 1.25em title, typography mirroring the site's
 *         single-photo pages, plain TWTIS mark bottom-center as the exit.
 *
 * Targets the Kathy theme (UXBARN) with the twtis portfolio templates.

 * centers #main-container (max-width 830px, width 90%). We hide the header at
