# Static generation reads Payload data. BuildKit mounts keep credentials out of
# layers and image history; migrations run separately through the migrator —
# the deploy script applies them BEFORE this build (OPS66: static routes read
# the new schema, so the build must see a migrated DB).
#
# OPS99: Generate importMap with dummy S3_* envs BEFORE next build.
# This ensures the production image always has the S3ClientUploadHandler entry,
# eliminating the class of bugs where the admin goes blank (OPS69/OPS72/OPS73).
# The dummy values are safe because Payload's generator doesn't connect to S3.
# Shell prefix assignments bind to a single command, so each side of the `&&`
# declares its own env: the generator runs through `pnpm generate:importmap`
# (which owns the `--conditions=react-server` the Payload CLI needs to import
# server-only modules), and `next build` carries the standalone flag itself.
