/**
* @module runner/recorderSetup
* @description Reserved namespace for a future extraction of recorder
* setup helpers shared between `startRecording` and `switchDevice` in
* `recorder.js`.
*
* **CURRENT STATUS — empty placeholder.** The DIF-015c Gap 5 work in
* PR #8 inlined the helper as `_attachAndOpenRecorderPage` /
* `_finishOpenRecorderPage` inside `recorder.js` itself rather than
* extract it to a separate module — the binding closure, pageAliases
* map, and screencast handle would need to be threaded through a
* shared options bag, which is more refactor than the PR's scope
* supported.
*
* This file exists because an early Phase D edit created it as a
* placeholder before the inline-helper approach was chosen. It is
* intentionally non-functional (no exports) so importing it is a
* no-op; bundlers will tree-shake it out of the final build.
*
* TODO(DIF-015c-FollowUp-1): delete this file or populate it with the
* shared setup helper. Tracked in ROADMAP.md under DIF-015c
* maintenance follow-ups. Until then, the duplicated binding setup
* in `recorder.js:_attachAndOpenRecorderPage` is "intentional, keep
* in sync" — see the file's own JSDoc for the maintenance contract.
