Logan CusanoandClaude Sonnet 5 d60fef67ad c2-core: add CORS middleware so the browser can call the REST API (#110)
The Archive page's GET /calls/search failed its CORS preflight (OPTIONS -> 405, no Access-Control-* headers). Allow the app origin(s) explicitly for the standard methods and the authorization/content-type headers.
