/* Ceteris Atlas: shared stylesheet.
 *
 * VERSIONED FILENAME ON PURPOSE. sw.js is cache-first for every non-page,
 * non-JSON request, and Hostinger's edge sets max-age=604800 on CSS, so a
 * stylesheet served from a stable path would be frozen in a returning
 * player's browser for a week. The house rule is that static assets only
 * change by changing filename. Any edit to this file ships as atlas-v3.css
 * with every page repointed; build_atlas.py does the repointing.

/* Three sections, so a three-tab switch rather than a row of pills. Games is
 * what you play, Learn is the economic-history modules, Data is the country
 * numbers behind both. A pill row grows every time something is added and
 * stops reading as a map of the site, which is the thing a visitor needs to
 * understand in the first second; a fixed grid cannot grow by accident.
 * The same markup is inlined in games.html, which carries its own stylesheet,
 * so a change here needs the same change there.
 * v2 to v3: two columns became three. Shipped as a new filename because
 * Hostinger edge-caches CSS for seven days. */
