⏱️ Autoloading Modules for Lazy Loading

Use autoload or Rails’ autoload_paths to delay loading large modules until they're first referenced. This decreases memory usage and speeds up boot time, benefiting monolithic applications with numerous optional components.

# lib/analytics.rb
module Analytics
  autoload :Tracker, 'analytics/tracker'
  autoload :Logger,  'analytics/logger'
end

# Usage
Analytics::Tracker.new.track_event(...)

Rails automatically handles autoload for files under app/, but custom libs benefit from explicit autoload declarations.
