/**
 * This project's own styling, on top of the site's stylesheet and the tools
 * stylesheet from the site's tools/assets/css/style.css.
 *
 * Everything here is either the option grid (which every tool page in the site
 * defines for itself, at its own column width) or something only a laser page
 * has: the two previews, and the footer this project carries instead of the
 * site's.
 *
 * Nothing here invents a colour. The tools stylesheet has no .btn rule, so
 * buttons are .primary / .secondary inside .actions -- a Bootstrap .btn comes
 * out invisible on the dark card.
