name: CI — Lint & Test

# Runs on every PR and every push to main.
# Three jobs in parallel:
#   1. PHP Lint — syntax check across supported PHP versions
#   2. PHPCS — WordPress coding standards (non-blocking during theme rollout)
#   3. PHPUnit — runs the theme's test suite against the WordPress test framework
