/**
 * home_page.css
 *
 * - Defines the design-token :root variables for both light and dark themes.
 *   These tokens are the SINGLE SOURCE OF TRUTH; component CSS files
 *   read them via `var(--*)` and MUST NOT redeclare :root.
 * - Declares the @property animations used by the conic-gradient hairlines
 *   on the compose box and featured posts.
 * - Owns the page-level layout grid (3 columns -> 2 columns -> drawer).
 * - Owns the in-feed tab bar and feed-meta strip rendered by home_page.js.
 * - Owns the global notifications-toast container styles.
 *
 * Component CSS files (topnav.css, post_card.css, etc) own their own
 * BEM namespaces and never style anything outside that namespace.
