/* vibe.css — site-wide atmospheric layer.
 *
 * The site is one thing. Six small touches make it feel like one:
 *
 *   1. Vignette       — subtle radial darkening at the edges, like a lantern
 *   2. Grain          — faint paper texture so flat surfaces breathe
 *   3. Transitions    — fade pages instead of jump-cut
 *   4. Watermark      — chi-rho ghost behind major empty states
 *   5. Hover lift     — every card subtly rises under attention
 *   6. Reading rhythm — text-wrap balanced, max-widths capped, lines breathe
 *
 * All effects respect prefers-reduced-motion. Nothing depends on JS.
 * Layered on top of styles.css / mobile.css / lens-polish.css.
