/*
 * shelf.css: the series front page (/index.html) and nothing else.
 *
 * Kept out of site.css because none of it is reused: the episode pages never
 * render a shelf, and the shelf never renders a hero, a kit or a beat. site.css
 * supplies every token used here (--ink, --rule, --display, --pad, .wrap,
 * .eyebrow), so this file only adds layout.
 *
 * One card per row on purpose. The whole genre is visual, the card image is a
 * purpose-built 1200x630 rather than a screenshot, and a grid of small tiles
 * would make the images too small to be the argument for opening them.
 *
 * Read alongside: index.html (the only page that loads this), assets/site.css
 * (tokens and shell this builds on).
