#!/usr/bin/env sh
# bash/install.sh — give bash the dotfiles shell helpers (opr/opc/opd/opl/ops,
# grmb, and secrets.env loading).
#
# WHY: those helpers lived only in the managed ~/.zshrc, so on a host that
# keeps bash as its login shell they silently did not exist. Omarchy is that
# host: it ships its own ~/.bashrc and default rc, and zsh/ cannot install zsh
# there (no dnf/apt). secrets/ still wrote secrets.env, but nothing loaded it,
# so every vault-backed variable was simply unset in new shells.
#
# Unlike zsh/, this never owns ~/.bashrc -- the host's rc stays in charge. It
# copies bash/dotfiles.bash to ~/.config/dotfiles/ and adds one marked source
# line, the same pattern mcp-config/ uses. Skipped when there is no ~/.bashrc
# (a zsh-only box has no use for it). No sudo. Idempotent.
