name: RUN.world Playground (local testing)
description: >-
  Playground runs your game on a local Vite dev server while SDK calls hit the
  RUN.world playground backend, letting you exercise storage, profiles,
  leaderboards, purchases, multiplayer, simulation, and other SDK APIs before
  deploying a build. Playground data is separate from production and may be
  reset periodically.
modes:
- name: playground
  description: >-
    Local Vite dev server with the rundotGamePlaygroundPlugin() Vite plugin
    injected only during `vite dev`; the local page gets a RUN.world toolbar for
    sign-in, player switching, and environment status.
  activation: "add rundotGamePlaygroundPlugin() next to rundotGameLibrariesPlugin() in vite.config.ts"
  backend: RUN.world playground backend (separate from production; may be reset)
- name: production
  description: Live RUN.world platform reached after `rundot deploy`.
setup:
  install:
  - "npm install @series-inc/rundot-game-sdk@latest"
  - "npm install --save-dev vite typescript firebase@^12.12.1"
  optional_iap:
  - "npm install --save-dev @revenuecat/purchases-js@^1.39.1  # only for testing IAP/subscriptions in Playground"
  run: "npm run dev  # Vite; SDK calls are mocked by default until the playground plugin is configured"
auth:
  api_key_prefix: "rk_"
  api_key_scope: per-game
  notes: >-
    Per-game rk_ API keys are used for headless CI/CD (rundot login --api-key).
    Key management and some prod-only tooling (e.g. image utilities) reject
    rk_ sessions and require an interactive owner login.
test_values:
  note: >-
    RUN.world publishes no fixed test cards, test tokens, or fixture values;
    Playground uses live player sign-in against a reset-able backend. No
    synthetic payment credentials are provided in the docs.
