Summary

Makes Share on X the only action on the Base Runner (/vibenet/demos/200) game-over screen, and removes the onchain leaderboard.

Share button (following BDS, base/bds)

• Uses the primary variant (Base Blue fill, same as BDS tone="brand") with the BDS x-twitter icon. The icon is copied into app/components/ui/icons.tsx (this repo hand-writes its icons).
• No surrounding panel; it sits directly on the game's road strip, centred under the game-over card.
• Sized and placed in game space: a ResizeObserver measures where the canvas draws (it letterboxes with object-contain), so the button keeps the same proportion to the card at any screen size. It is 36 px tall with a 13 px label on phones and in the 800 px inline layout, and up to 64 px with a 22 px label on large screens.

Onchain leaderboard removed

• Removes the "New onchain best! / Post N onchain" prompt, a duplicate Post button (with a stray copy of the score bar) in the high-scores header, the "Onchain high scores" section, the 12 s board polling and the throwaway score wallet.
• Deletes lib/leaderboard.ts (+ test) and contract/ (BlockRunnerScores source, ABI, deploy script); nothing else imported them.
• Reason: the scores contract at 0x2441…e07d no longer exists on vibenet (eth_getCode returns 0x, likely a devnet regenesis), so every board read failed, every run showed the Post prompt, and every post would have failed.

The local "Best" score (stored in the browser) is unchanged.

Screenshots

Game over at 1920×1000 (immersive): the button scales with the game.

Inline layout at 1280 px, with the high-scores section gone below the game:

Test plan

• npx vitest run app/vibenet/demos: 227/227 pass.
• npx eslint app/vibenet/demos/200 app/components/ui/icons.tsx: clean. tsc --noEmit: no new errors (only the existing missing next-env.d.ts PNG-type error in this checkout).
• Playwright against next dev: forced a game over at 1920×1000, 390×844 and the inline 1280 layout; checked the button size and position, that Share on X is the only game-over button, that the high-scores section is gone, and no page errors.
