 * A journey of three hundred pictures showed them as one grid, so laying out
 * the page for one day meant scrolling past every other day to find its
 * pictures. What these check is that the browser can be narrowed to one
 * entry, to the pictures no entry claims, and to what just arrived; that the
 * search still applies on top; and that a picture uploaded here lands where
 * the panel says it will, the entry the filter names or the gallery when it
