/* ════════════════════════════════════════════════════════
   CUSTOM PROVIDERS — add a genuinely new provider/model here, entirely in
   index.html. No native code change, no separate JSON file, no app build.

   Requirements for a new entry:
   - The endpoint must be an OpenAI-compatible chat-completions endpoint
     (POST {model, messages, stream}, SSE-style streaming deltas), reachable
     via fetch() from the WebView (i.e. it must send CORS headers allowing
     this origin — verify this per provider before relying on it).
   - `endpoint`, `apiKeyHeader`, `apiKeyPrefix` are sent to native code once
     (via Bridge.setCustomModelOverrides, called automatically below) purely
     so the native reason()/reasonWithCustomJsModel() dispatcher recognizes
     the model id and routes back into JS - native code never calls the
     endpoint itself, it only stores this definition and the user's API key
     (SharedPreferences; see CustomModelPreferences.kt) and hands both back
     to _callOpenAiCompat() in this file, which performs the actual fetch().

   Fields:
   - id             (required) unique string, e.g. 'OPENROUTER_LLAMA_4'
   - displayName    (required) shown in the model picker
   - endpoint       (required) full URL, e.g. 'https://openrouter.ai/api/v1/chat/completions'
   - modelName      (required) the "model" field sent in the request body
   - apiKeyHeader   (default 'Authorization') HTTP header used to send the key
   - apiKeyPrefix   (default 'Bearer ') prefix prepended to the key in that header
   - supportsScreenshot (default false) whether to send the screenshot image
   - supportsTopK   (default false) whether to send top_k
   - supportsThinking (default false) whether to send enable_thinking/thinking_budget
   - stream         (default true) whether the endpoint streams SSE deltas
   - hint           (optional) short text shown under the model name in the picker

   Example:
   { id:'OPENROUTER_LLAMA_4', displayName:'Llama 4 (OpenRouter)',
     endpoint:'https://openrouter.ai/api/v1/chat/completions',
     modelName:'meta-llama/llama-4-scout', apiKeyHeader:'Authorization',
     apiKeyPrefix:'Bearer ', supportsScreenshot:true, supportsTopK:false,
     supportsThinking:false, stream:true, hint:'OpenRouter' }
