TL;DR: Turn websites into planets and organize them into systems, galaxies and universes. The web app includes immersive exploration, a searchable atlas, planet/star details, optional flight and a browser-local editor. Its provider-neutral catalog keeps the bundled Demo separate from your Local universes; a Firecrawl search adapter demonstrates normalization. Account authentication, synchronization, live ingestion and the Go API remain planned. New accounts will start with zero planets.

| Explore the map | Inspect and navigate |
|---|
| Focus Earth within its intact system | Find planets in the searchable atlas |
| See the universe at a glance | Explore the Milky Way catalog |
| Zoom into a sky region | Inspect TRAPPIST-1 |
| Explore 16 nearby systems | Navigate to visible neighbors |

Project structure
web/ — Next.js, React, TypeScript, and Tailwind CSS, with modular i18n and shared Velrino UI components.api/ — Planned Go API.evals/ — Planned Python evaluations.
Design system
Explore the shared Velrino UI gallery for colors, typography and interactive components. Design-system links open it in a new tab with the active language, keeping the universe open. Search components from Go to and adjust language, colors and surfaces in Settings. Existing /design bookmarks redirect there.
Use these shared components and tokens when building new pages. The visual reference guide explains the design direction, and the web guide covers component usage and module structure. The browser selects the initial interface language; ?lang=en, ?lang=pt-BR or ?lang=fil overrides it on every page. The global language dialog switches languages without reloading. See the localization contract.
Universe demo
The home provides a mobile-first, full-screen 3D demo with 767 real planets and 1,270 entities across 450 systems, 32 navigation regions and 20 real galaxies. Eight planets belong to the Solar System and 759 are confirmed exoplanets from the NASA Exoplanet Archive. The real IAU constellation regions are sky-direction groupings, not physical clouds. Only the Milky Way contains planetary systems. Names/descriptions are sourced. Mission controls → Pause offers Proportional sizes by default, based on available stellar and planetary radii, or Illustrative sizes with larger stars. Orbital distances remain adjusted for exploration. The choice is saved locally; ?scale=proportional or ?scale=illustrative overrides it. Unknown radii use unscaled symbols in Proportional. Colors, surfaces, galaxy shapes and motion remain illustrative. Solar/tour identity is preserved. Source selection and bounds keep the demonstration independent of Local catalogs and live ingestion.
