## [2026-04-17] Numpad Enter plays audio in classify TUI
The Enter-key handler in `tui/classify.go` now matches both `tea.KeyEnter` and
`tea.KeyKpEnter`, so the numeric keypad's Enter key plays the current segment
just like the main Enter key (and respects Shift for half-speed playback).
This lets the user keep their hand on the numpad while labeling.
Previously, terminals that disambiguate keypad keys (e.g. via the Kitty keyboard
protocol that bubbletea v2 negotiates) delivered numpad Enter as `KeyKpEnter`,
which fell through to the single-character binding path and did nothing.

**Files changed:**
- `tui/classify.go` — Enter-key branch in `handleKey` now ORs `KeyKpEnter`
