# pipelines/gitea/setup.sh — Automate Gitea initial setup via REST API
#
# Steps:
#   1. Create admin user (idempotent — skip if already exists)
#   2. Create OAuth2 application for Woodpecker CI (idempotent — reuse if exists)
#   3. Create stonks-oracle repository (idempotent — skip if already exists)
#
# Outputs OAuth2 client_id and client_secret to stdout and to
# gitea-oauth2.env (sourceable by runmefirst.sh).
#
# Requirements: 1.1, 1.2, 1.5, 2.3
