/**
* MyShowsPage - Two-panel file-explorer style view
* Left panel: list of subscribed shows
* Right panel: episodes for the selected show
* MyShowsPage — yazi-style 3-pane view (canonical reference migration).
*
* pane 0 (parent) — subscribed shows
* pane 1 (current) — episodes of the focused show
* pane 2 (preview) — detail of the focused episode
*
* Movement (j/k, gg/G, page-jumps) and selection (space, v) are driven by the
* Shell router via the `nav.action` event bus; this page only subscribes and
* translates actions against its own data. h/l swipe between panes is handled
* by the Shell (nav.swipe). The focused row is read from nav.focusedIndex(pane)
* so the page is purely reactive.
