Server CLI Flags

Flag	Purpose	Default
--port	Server listen port	3000
--log-dir	Log directory	empty
--version	Print version and exit	false
--help	Print help and exit	false

Server Environment Variables

Variable	Purpose	Default
PORT	Server listen port	3000
GIN_MODE	Gin mode	release unless debug
LOG_LEVEL	Log level	info
SESSION_SECRET	Session signing secret	random on startup
