#
# Squashes a whole codebase into one text file, skipping build artefacts:
#   • ignores node_modules, dist, .git, .turbo, .next, out
#   • omits lockfiles and *.min.* noise
#   • copies the result straight to the macOS clipboard (pbcopy)
#
# Example:
#   bash concat.sh ~/Projects/notarium-mcp mega.txt
#

root="${1:-.}"
out="${2:-bigcode.txt}"

# fresh file
> "$out"

# ----------- find everything we want (and nothing we don’t) -------------
