Generated from swaggo v2 annotations, committed rather than built into the
image: the runtime stage is scratch and adding codegen puts the toolchain
in the build. CI regenerates and diffs, so an annotation edited without
regenerating fails the build — without that the annotations would drift
while still looking authoritative.
Scalar is vendored rather than loaded from a CDN, because air-gapped
self-hosted installs are supported and a reference page that fails closed
offline is a support ticket.
