The files on the guard's legacy list build new WebServer(0, …) and read server.boundPort after start(), as sse-tile-grid-filter does. Files with several servers read each server's own port; quick-start's local helper lost its port parameter so the literal 0 sits where the server is built. Header comments that named a port say "ephemeral". No assertion changed except where it embedded the port.

Real-browser regression coverage for the previous commit:
- SplitTerminalPane connects onto an already-quiet session and shows its
existing scrollback with no new output, proving the ?full=1 fetch (not
a live echo) populated the pane.
- openSplitPane() force-resizes Pane A synchronously as part of opening
a split.
- Dragging the divider force-resizes Pane A once, at drag end.
