 # `shopify app dev` never starts the Remix app at all — it only runs the
 # theme/function/UI-extension dev servers — which is why the embedded
 # admin app home never loaded no matter what URL configuration was tried.
+#
+# Content below matches shopify.web.toml.liquid (the original scaffold
+# template for this file, still present at the repo root) rendered for
+# npm — that .liquid file was apparently never actually run through
+# `shopify app init`'s templating step when this repo was first set up,
+# which is the real root cause of this file having been missing entirely.
+# predev/dev's prisma steps mean `shopify app dev` keeps the generated
+# Prisma Client and the database schema in sync with schema.prisma
+# automatically every time it starts, rather than needing `npx prisma
+# generate`/`migrate deploy` run by hand after every schema change.
