Header.tsx has a disabled dev-console button inside a JSX comment and
IntegrationsSettings has a commented-out section literal. Four hits in
officer-web, all of them code nobody ships — and an area cannot reach zero while
a comment counts against it.
Only two shapes stripped, both unambiguous: block comments, and lines whose first
non-space characters are //. Stripping every // would eat the tail of any string
holding a URL. Verified the delta is exactly those four.
