The virtualized v3 Songs grid rebuilt its entire visible window (grid.innerHTML = _renderCardsRange(...) + a full wireCards pass) every time it slid by one row. Each row-boundary crossing was therefore a heavy synchronous frame — reparse ~60 cards, re-attach hundreds of listeners, reflow — that stalled the main thread and buffered held-arrow key-repeats, flushing them in a burst. Testers saw the library "go super fast for a second then slow down," skipping "every so many scrolls," up or down, at the same spots each time. It hitched scrolling back up over already-loaded songs too, because the cost was DOM teardown, not fetching. renderWindow() now reconciles the window in place: it reuses the card nodes that stay on-screen and builds only the row that enters/leaves (~6 nodes per slide instead of ~60). Nodes are keyed by absolute index (data-idx) with a real-vs-skeleton + select-mode signature (data-sig) so hole-fills after a page fetch and select-mode toggles still rebuild exactly the nodes that changed. wireCards()'s existing data-wired guard then wires only the freshly-built nodes, so per-slide listener churn drops with it. Everything keyed off data-fn (favorites, ⋮ menu, right-click, selection, accuracy badges, A–Z rail) is unaffected. Follow-up to the stage-2 virtualized grid (#636 item 3). Frontend-only. Tests: tests/js/v3_songs_window_recycle.test.js — window stays [start,end) contiguous and in-window node identity is reused across a down-then-up scroll; select-mode toggle and a rail-seek jump rebuild correctly.
