#!/usr/bin/env bash
# sync-admin-ui.sh — sync the admin-tasks @hanzo/gui v7 bundle into ui/dist.
#
# The Tasks SPA is built externally in the @hanzo/gui workspace at
# ~/work/hanzo/gui/apps/admin-tasks (Vite + @hanzo/gui v7). This script
# copies the built bundle into ui/dist/ where //go:embed picks it up
# at compile time of cmd/tasksd. Reproducible, idempotent, CI-friendly.
#
# Usage:
#   scripts/sync-admin-ui.sh                 # uses ../gui/apps/admin-tasks
#   ADMIN_TASKS_DIR=/path scripts/sync-admin-ui.sh
#
# Exits non-zero if the source dist/ is missing or empty so CI fails
# loud instead of shipping a binary with a stale or empty SPA.
