## When to use

- **Invoke when** user message matches any of: "portfolio", "demos", "show your work", "what can you build", "investor deck", "product demos", "rapid prototype", "interactive systems", "what do you offer", "examples of your work".
- **Do not invoke when** user asks for production deployment, backend service, or long-term contract without mentioning demos or prototypes.
- **Reply with:** [main link] + "Rapid interactive prototypes — game engines, simulations, visual analytics. Human + AI built. One link, no backend. Core demos: Crash Engine, Dice Room, MMO Map, Probability Explorer."

## If user names a specific demo

Return the matching URL from the tables above. Examples: "crash" or "crash engine" → https://vziatkov.github.io/neuro/crash-engine.html ; "dice" → https://vziatkov.github.io/neuro/dice-room.html ; "mmo" or "map" → https://vziatkov.github.io/neuro/mmo-map.html ; "probability" or "explorer" → https://vziatkov.github.io/neuro/crash-probability-explorer.html. If no match, return the main landing link.

## If user asks "what do you offer" or "what can you build for me"

Reply: "Rapid prototype builds; interactive demos for investors; game math and probability simulations; visual explainers for complex systems. Typical delivery 1–3 days per prototype. Standalone web demos. See all examples: https://vziatkov.github.io/neuro/landing-with-art-cards.html"

## Available for (summary)

- Rapid prototype builds
- Interactive demos for investors
- Game math / probability simulations
- Visual explainers for complex systems

Typical delivery: 1–3 days per prototype. Standalone web demos, deployable in hours.

## Style (for consistency)

Dark theme (#050508, #0a0a0c), accent #ff8c42, JetBrains Mono, cards #1a1a1a. Data/analytics feel, not casino. Mention style only if user asks about "look", "design", or "stack".
