 * The catalog: one block of Alga Crater as a picture with 256 links on it.
 *
 * Its own file because Propshaft's `stylesheet_link_tag :app` includes every
 * stylesheet in this directory; application.css holds what every page shares.
 *
 * The tiles have no body of their own -- they are transparent squares over the
 * orbital image -- so everything that tells a reader which parcel they are on
 * is done here: a status tint, a hover fill, and a focus outline.
