{% sw_extends '@Storefront/storefront/page/checkout/summary.html.twig' %}

{#
  Injects milestone discount rows and a "✓ Free" shipping label into the
  checkout summary sidebar on /checkout/cart, /checkout/confirm, and order pages.

  We override page_checkout_summary_inner (a block directly in summary.html.twig)
  rather than blocks inside sw_include'd sub-templates, which are not reliably
  overridable across sw_include boundaries.

  Data source: page.extensions.ucMilestoneInfo
  Set by: StorefrontPageSubscriber::onStorefrontRender() BEFORE stripping.
  Falls through to {{ parent() }} when no milestone info is present.

  CROSS-PLUGIN NOTE: SellopsPostPurchaseUpsell (installed separately, NOT
  part of this plugin) overrides this SAME block in this SAME file to show
  its own discount row. Twig block inheritance only lets ONE override
  actually execute per render — whichever plugin's template ends up
  "outer" in the chain (not something either plugin controls) decides,
  and it normally would NEVER see the other plugin's row at all. So this
  block also scans for that other plugin's own `sellops_upsell_discount`
  line items (its real line item type — must stay exactly as-is to match)
  and renders that row too — regardless of which plugin's override happens
  to "win" the chain on a given install, the customer always sees BOTH
  discounts (if both happen to be active on the same order), never just
  one silently dropped.
