   Onyr.net — "Prism" theme.
   Chromanaryl rainbow on a Nocturne skeleton. Cyan #47BED6 accent.
   Home is the eye-candy (rotating color-wheel logo); reading pages are
   calm with FIXED rainbow accents. One animated ribbon rides the nav.
   Fonts self-hosted (Inter + JetBrains Mono). No third-party requests.
