# Build All Targets CI Configuration
#
# Controls board grouping, cache sizes, runner specs, and seeder targets
# for the build_all_targets workflow. Forks can customize this file to
# adjust for their infrastructure (e.g., lower cache sizes for GitHub's
# 10GB cache limit, fewer CPU cores for smaller runners).
