/**
 * 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.
 *
 * The same shape as laser/assets/css/laser.css -- the option grid, the preset
 * rows, the front-door cards, the preview stage -- under `.cnc-page` instead of
 * `.laser-page`, plus the few things only a router page has: the depth scale
 * under the shaded preview, and the toolpath legend, whose colours have to match
 * what the canvas draws.
 *
 * 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.
