/* ── CSP utility classes — заменяют inline `style="..."` атрибуты в chat.html ──
 *
 * 2026-05-13: Часть статических inline-стилей в chat.html переведена на эти
 * классы, чтобы уменьшить count'у style-src-attr CSP violations. Не флипаем
 * директиву в `'none'` пока chat.js innerHTML-строки с inline-стилями не
 * подчищены — это отдельный рефакторинг chat.js (split + event delegation).
 *
 * Конвенция:
 *   .is-hidden            — display: none (БЕЗ !important чтобы JS мог
 *                            переопределить через `.style.display = 'flex'`
 *                            на динамически показываемых модалках; см.
 *                            enterChat(), showQueue() и т.п.)
 *   .u-relative           — position: relative
 *   .u-width-0            — width: 0% (для прогресс-баров до анимации)
 *   .u-flex-row           — display: flex; align-items: center; gap: 6px
 *   .u-mt-{12,8,6,10}     — margin-top
 *   .u-mb-10              — margin-bottom: 10px
 *
 * Source order гарантирует выигрыш над дефолтными display-правилами
 * (`.chat-screen { display: flex }` и т.п.) — этот блок в конце chat.css.
