"""Foresportia tutorial: upcoming matches, markets and verified history.

This script is the canonical source used by the Foresportia documentation
tutorial at /api/docs/tutorials/football-dashboard.html. The page code blocks
and the downloadable file are both generated from this exact file, so they
never diverge. The ``# region`` / ``# endregion`` markers are non-functional
comments used by the documentation generator to slice out each step.

Install:
    python -m pip install --upgrade foresportia matplotlib

API key — Windows PowerShell:
    $env:FORES_API_KEY = "your_key"                          # current session
    [Environment]::SetEnvironmentVariable(
        "FORES_API_KEY", "your_key", "User"
    )                                                        # persistent

API key — macOS / Linux:
    export FORES_API_KEY="your_key"                          # current session
    echo 'export FORES_API_KEY="your_key"' >> ~/.zshrc       # macOS/zsh
    echo 'export FORES_API_KEY="your_key"' >> ~/.bashrc      # Linux/bash

To keep the main path at two API calls, also set the competition:
    $env:FORES_LEAGUE_CODE = "SUE"       # Windows PowerShell
    export FORES_LEAGUE_CODE="SUE"       # macOS / Linux

Without FORES_LEAGUE_CODE, a single-competition Developer key can be detected
with list_leagues(), at the cost of one extra request.
