// Front-controller API hand-off.
//
// Apache (.htaccess) and the generated nginx include send /api/* directly to
// api/index.php. Servers that instead route every unknown path to this front
// controller (DDEV/nginx without the include, PHP's built-in server, default
// LiteSpeed) would render the theme 404 for /api/v1 - which surfaces in the
// sidebar autocomplete as "An error occurred during search." Dispatch before
// lib/main.php so api/index.php keeps its own bootstrap order.
//
// __DIR__ is passed explicitly because SCRIPT_NAME is not always the front
// controller: PHP's built-in server reports the nearest matching file (for
// /api/v1 it reports /api/index.php) while nginx/Apache report /index.php.
