#!/usr/bin/env bash
# install.sh — idempotent fleet package installer for the ~/.omp repo deployment.
#
# Model: packages/*.pkgs declare DESIRED state per host. This script computes
# (desired − installed) and installs only that delta via pacman/yay. It NEVER
# removes anything. Re-running after a fresh install, or casually months later,
# is safe by construction.
#
# Modes:
# install.sh check (default): print the plan for this host, write nothing
# install.sh --apply install the delta + run host-gated enablement actions
#
# Host selection: --host <name> overrides $(hostname); an unknown host gets the
# common manifest only — wrong-host runs are a no-op, not a hazard.
#
# Sudo: set FRANK_SUDO_PW in the environment for non-interactive runs;
# otherwise sudo prompts normally. The value is never stored in this repo.
