.botenv

# .botenv — Non-interactive-safe core bootstrap for botfiles.
#
# This file sets up the minimal environment (secrets, PATH, EDITOR, TERM,
# UV_BIN) needed by any shell context: interactive terminals, SSH commands,
# agent exec paths, cron jobs, and non-interactive hooks.
#
# It is POSIX-compatible and safe for both bash and zsh.  The interactive
# layer (.botrc) should source this file and then add aliases, prompts,
# and other interactive-only configuration on top.
#
# Double-source guard: idempotent within the current shell.
