<title>Baghchal Bot API</title>
<!--
  The Bot API, running on a *static* Hugging Face Space.

  A static Space serves files and runs no process, so there is nothing here to answer an HTTP
  request from another origin. What this page does instead is run the deployed server's OWN
  reply builder (bagh_server.botapi.bot_reply) under Pyodide, in the visitor's browser, and
  render the exact JSON it produces. Open it with a position and read the response:

      api.html?obx=TXXXT/XXXXX/XXXXX/XXXXX/TXXXT g @20 c0 -

  Same schema as the hosted API -- {"input", "obx", "move"} plus side/bot/terminal -- because it
  is literally the same function, not a re-implementation that could drift from it.

  Query params: obx (position), bot (default phantom), ms (think time), pretty=0 for one line.
