/*
 * Homepage hero (index.php): a full-bleed photograph under a navy gradient.
 *   Left   the name, the promise, two calls to action, a "log in" line and the society in numbers.
 *   Right  two frosted-glass cards: the next event (when one is ahead) and the newest published piece
 *          (or a line of Tagore's Gitanjali while nothing is published).
 *   Foot   a gently curved edge and a scroll cue.
 * Every class is hm-hero* and scoped under .hm-home; colour and type tokens come from css/home.css (.hm-home { --hm-… }).
 * Light page, dark hero. Motion is transform / opacity only and is switched off for prefers-reduced-motion.
