 * Design language: «Обложки» — a neutral gallery chrome, all colour comes from

 * composition class (co-*) per title; both are computed server-side by
 * CoverService. Themes: light gallery / warm-charcoal dark, switched by the
 * `dark` class on <html> (theme-init.js + app.js). Covers do NOT change with
 * the theme — only shadows and edges adapt. */
