.zprofile

# ──────────────────────────────
# Homebrew environment setup (login shell only)
# ──────────────────────────────

# Notes:
# - `.zprofile` is only loaded for login shells (`zsh -l`).
# - Keep this file silent and minimal (no prompts / no UI / no network).
# - `brew shellenv` configures more than just `PATH` (e.g. `MANPATH`), which is why it lives here.
# - This repo also prepends `/opt/homebrew/bin` (and GNU "gnubin" shims) via
#   `scripts/_internal/paths.exports.zsh` so non-login shells can still find `brew`.
#   See `docs/guides/startup-files.md`.
