Build a polished, playable skateboard game in the current directory. You own this game directory only. Use HTML/CSS/JavaScript (Canvas or WebGL is fine), with no backend dependency. Make it fun: a controllable skater, acceleration/braking, jumping/ollies, ramps or obstacles, collision/bail and restart, a score or trick-combo system, and clear on-screen controls. Give it a distinctive visual style. Support keyboard controls and an usable smaller-screen layout. Do not just draw a static mockup.

Read the LookingGlass SKILL.md and use that headless-browser skill to debug your implementation. Use your SKATE_PORT environment variable for the local HTTP server. Your BROWSE_STATE_FILE environment variable provides an isolated LookingGlass browser; preserve it in subprocesses. Start the server, play through the controls and a restart, inspect console errors, take screenshots, and use your read tool to actually inspect the screenshot images. Fix problems you observe and leave the playable server running. Save screenshots and a concise TESTING.md describing what you tested and any limitations in this directory. You have image input enabled; do not claim screenshots are unavailable without attempting to read one.

The attached image is a vision check: first state its two shapes/colors/left-right positions and its exact printed text. Then implement the game; do not wait for further approval. Do not touch other projects, modify model serving, kill other sessions, or publish anything remotely. Do not run rm -rf. Deliver the local URL when ready.
