# frozen_string_literal: true

# Reusable sync summary component for provider items.
#
# This component displays sync statistics in a collapsible panel that can be used
# by any provider (SimpleFIN, Plaid, Lunchflow, etc.) to show their sync results.
#
# @example Basic usage
#   <%= render ProviderSyncSummary.new(
#     stats: @sync_stats,
#     provider_item: @plaid_item
#   ) %>
#
# @example With custom institution count
#   <%= render ProviderSyncSummary.new(
#     stats: @sync_stats,
#     provider_item: @simplefin_item,
#     institutions_count: @simplefin_item.connected_institutions.size
#   ) %>
