- netlify/functions/ai.mjs: POST /api/ai runs against Netlify's AI Gateway —
Netlify injects OPENROUTER_API_KEY + OPENROUTER_BASE_URL into Functions, so no
key is managed or shipped. Curated model allowlist, best-effort per-IP
throttle, CORS for web + Capacitor, and SSE streamed straight through.
- sasquatchBrain: call the proxy instead of OpenRouter directly; drop
VITE_OPENROUTER_API_KEY entirely; PROXY_MODELS set to the slugs that actually
work via the gateway (its ZDR policy blocks gemini/anthropic/gpt-4o-mini).
- netlify.toml: [functions] directory.
- Verified in production: POST https://skate-spots.org/api/ai -> 200.
