Minimal connection

Detect, connect, open, focus, close

Idle

This is the cleanest “hello world” for RTO 7.13.0: it detects the extension, opens or reuses one controlled tab with a stable tabKey, proves control with a small overlay move, then lets you focus or close the same tab.

What to expect

The target page should show the banner WARNING : This tab is controlled by RTO. The open button reuses the same tabKey on purpose, so pressing it again focuses the existing controlled tab instead of creating a pile of clones.

Flags & config

Flag	Meaning
`window.RTOdetected`	Set to `true` when the detector has found the extension.
`window.RTOconnected`	Set to `true` once a message channel has been opened.
`window.RTO_PAGE_ORIGIN`	Optional. The default `rto-page` origin is the normal 7.13.0 page-side origin.
`window.tabKey`	The logical key of the controlled tab. Reusing it is how `openTab` reopens the same lane cleanly.

Quick log

This keeps the flow beginner-friendly: detect, connect, open, focus, close, and a tiny overlay proof once the target form is reachable.
