/*
 * Shared landing-page stylesheet for USelf Labs game/app sub-sites.
 *
 * This file is IDENTICAL in every landing page folder — it is the template's
 * shared layer. Per-game look is set entirely by overriding the custom
 * properties in the `:root` block of that site's index.html, so nothing here
 * needs editing when cloning a new site.
 *
 * Update flow: edit _template/styles.css, then re-copy it into each site
 * folder (./new-site.sh --sync).
 *
 * No build step, no framework, no external requests — one file, ships as-is.
