The app-test page could render blank processor/mac verbiage when pnpm did not supply npm_package_config_verbiage_* in the runtime environment. Fall back to package.json config and the page-level computed value so the subtitle and description stay populated in builds and production.
Constraint: Must not change scanner behavior or app-test submission flow
Rejected: Patch only the Vue page text | leaves the public runtime config inconsistent for other consumers
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep publicRuntimeConfig resilient to missing npm_package_config_* env values until the config source is normalized repo-wide
Tested: pnpm run typecheck (workspace); node --input-type=module import of publicRuntimeConfig (workspace)
Not-tested: Full browser rerun for this exact commit beyond the already-green production smoke suite
