 * in the document, so it floats over the two screens picks are collected
 * from and under search, the stories, onboarding and the gate — the pill is a
 * tool of browsing, not of any one screen — a circle in the nav's own row
 * on the fixtures tab, a pill on the fixture page, one box morphing between
 * the two, hidden everywhere else. The sheet is the slip results
 * screen's bookie picker chrome (scrim, stack layer, tall panel, circular X
