/* Маскот сайта — Буквица, кошкодевочка-хранительница библиотеки ER.IIIBA.RU (www/i/mascot/guard.svg, avatar.svg; буква «R» на её книге — часть рисунка, не менять).
 * Страница запрета копирования /shield/blocked (views/shield/blocked.php) и оверлей стража в читалке (www/js/modules/shield.js).
 * Цвета рисунка — CSS-переменные --mascot-* (в SVG у каждой есть запасное значение, поэтому <img> тоже выглядит правильно).
 * Тёмная тема: включается свечение за фигурой и светлые штрихи движения — тёмный контур не теряется на тёмном фоне. */
