Module: runner/recorderSetup

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.
