/**
|
||||
* Standalone Playwright check that mirrors the production exec-panel layout
|
||||
* and asserts that:
|
||||
*
|
||||
* 1. The Activity scroll container is actually scrollable
|
||||
* (scrollHeight strictly greater than clientHeight).
|
||||
* 2. After scrolling to the maximum allowed position
|
||||
* (scrollTop = scrollHeight − clientHeight), the LAST entry is fully
|
||||
* contained inside the container's visible rect — i.e. its bottom
|
||||
* edge sits at-or-above the container's bottom edge.
|
||||
* 3. The outer panel-body can still scroll past the focused card to
|
||||
* reveal sibling cards (regression guard for the `overscroll-behavior`
|
||||
* / `min-height: 0` fixes).
|
||||
*
|
||||
* The fixture is a static HTML page that copies the production CSS for the
|
||||
* panel and the progress timeline so we are testing the same cascade the
|
||||
* real UI sees, without spinning up the React app.
|
||||
*
|
||||
* Run: node --import tsx ./tests/exec-panel-scroll.spec.ts
