/*
 * Webmaster portal stylesheet.
 *
 * Deliberately not shared with the public site's assets/style.css. That one is
 * a search results page — big type, lots of air, tuned for reading prose. This
 * is a console: dense tables, status chips, forms, and a left rail that stays
 * put. Sharing a stylesheet between the two would mean every change to a table
 * cell risks moving a search result.
 *
 * Light and dark both come from the custom properties below, so a rule almost
 * never needs to name a colour twice.
