Two additional window-level keydown handlers were also capturing keys when the pitch input (or any input/select/textarea) was focused: 1. The key remap handler (capture phase) was eating all keydown events 2. The game lane input handler was calling preventDefault() on keys like f, g, h, j, d, k, l, space — which are needed for typing pitch names Both now skip when activeElement is an INPUT, TEXTAREA, or SELECT. https://claude.ai/code/session_01TLvDyKzUQekd9hzFuEJ5YX
