A local preview of the Arc Ecosystem Program — a scoped open-source contribution program. Maintainers submit repositories for review; accepted repositories get their own dashboard where the maintainer posts issues and picks one contributor per issue. Contributors browse, apply with a plan, and earn points that split the wave pool in USDC.

The ecosystem is defined in one place: src/program.ts holds the name, chain, and reward asset. Swapping programs is that file plus the repository fixtures in src/model.ts.

npm.cmd install
npm.cmd run dev

Two clearly separate kinds of screen:

Public — top nav, centred content, no dashboard chrome.

Workspaces — fixed left rail, scoped to one role or one repository.

The maintainer area is a separate session from the contributor one — signing in as a contributor never opens it, and vice versa. Beyond that:

1. Sign in at /maintainer/login.
2. Submit a repository. It enters Pending. No dashboard opens.
3. The repository must be accepted before its dashboard exists. Review is simulated locally because the preview has no backend reviewer.
4. Each accepted repository gets its own dashboard — its issues, its proposals, its assignments.

The gate is enforced on the route, not just in the UI: a direct URL to a pending repository's dashboard, or to a repository owned by a different maintainer, redirects away.

Dark by default, with a violet accent. One neutral ramp plus one accent drives both themes, so light and dark come from the same tokens.

Sharp edges. Every radius token is 0, so buttons, cards, chips, inputs, modals and avatars are square. Only true dots (status indicators, language dots, aurora blobs) stay circular.

The public navbar is a sticky bar with a dismissible announcement strip above it, a slash-separated link group, and a border that only appears once the page is scrolled. It collapses to a sheet below 860px. Type runs on eight steps topping out at 30px, controls on three heights, spacing on a 4px grid. Inter for UI, JetBrains Mono for identifiers only. Motion is handled by motion on one easing curve.

Ported into src/bits.tsx, src/bits-ui.tsx and src/bits-gl.tsx: GooeyNav (SVG goo filter, blob tracks the active item, particles burst on click), MoltenMetal (WebGL fragment shader, domain-warped fbm; pauses off-screen and falls back to a CSS gradient without WebGL), Lanyard (spring-physics badge on a cord, draggable), CardSwap, BounceCards, ProfileCard (pointer tilt + holographic sheen), InfiniteSpiral and LogoLoop. The public navbar is a floating pill.

React Bits (reactbits.dev) ships as copy-paste source rather than an npm dependency, so src/bits.tsx holds its patterns re-implemented against these tokens: Aurora, DotGrid, GradientText, ShinyText, SplitText, CountUp, SpotlightCard, StarBorder, Magnet, ClickSpark, RotatingText, AnimatedContent, Marquee, GlareHover, TiltedCard and ScrollProgress. Every scroll-triggered component falls back to fully visible under prefers-reduced-motion, so content is never left hidden.

The hero visual (src/hero-visual.tsx) is an animated contribution pipeline — proposal, assignment, pull request, acceptance, settlement — looping in DOM. It is not Rive: a .riv is a binary artboard exported from the Rive editor, so it has to be authored there. Drop one in and swap HeroVisual to render it; the pipeline stays as the fallback.

The landing page lays these out on a six-column bento grid (.bento / .box with w2/w3/w4/w6 spans) — large boxes with generous padding and display-scale figures, rather than uniform small cards.

With the dev server running:

npm.cmd run build
npm.cmd run test:smoke -- http://localhost:3000

The smoke test covers the public explore surface, search/tabs/filters, the contributor apply and persistence path, the separate maintainer sign-in, the submit-then-review gate, per-repo dashboards scoped by owner and acceptance, proposal assignment, theme persistence, the mobile drawer, and horizontal overflow across 15 routes at five widths.

Organization avatars are the real ones, pulled from https://github.com/<org>.png. An org that does not resolve falls back to a letter tile, so a repository submitted under a made-up handle still renders correctly. Language dots use GitHub's own language colours.

Everything is local. There is no GitHub OAuth or sync, no database, no wallet, and no USDC transfer. Repository review is simulated because the preview has no reviewer.

The seeded repositories are real, existing open-source projects used as reference examples so the directory renders with genuine avatars and plausible metadata — their star counts, topics and update times are fixtures, and their presence here implies no affiliation with, or participation in, any program. Sample contributors (nadia.dev, kwame-o, lucia-m, tobi.k) are fixtures so the maintainer flow has candidates to choose between.
