// this plugin ships runs the same way on every site, and no code here asks
// the Freemius SDK what the site has bought. AnswerRails Pro is a separate
// download from answerrails.com, and the modules it adds load through their
// own file, which is absent from this plugin.
//
// Freemius step-18 guard (#95): when AnswerRails Pro is activated while this
// plugin is still active, Freemius loads Pro's main file first and
// auto-deactivates this one — during the swap BOTH main files can load in
// one request. The already-loaded SDK instance wins; the second file only
// re-points the basename. Everything else — snippet, constants, bootstrap —
// lives inside the else, so nothing redeclares.
