/**
 * Split button: a main action plus a ▾ toggle that opens a menu of related actions
 * (NOTES 2026-10-31). Each action can carry a keyboard `shortcut` — the main one shows
 * in the main button's tooltip, item ones as a right-aligned hint in the menu — and all
 * of them are bound document-wide (same scoping as `<baht-button shortcut>`).
 *
 *   <baht-split-button label="Save" shortcut="alt+s"></baht-split-button>
 *   el.items = [{ value: 'save-close', label: 'Save and close', shortcut: 'shift+alt+s' }];
 *   el.addEventListener('baht-click', save);
 *   el.addEventListener('baht-select', (e) => run(e.detail.value));
 *
 * Keyboard: ↓ / Enter / Space on the toggle opens on the first item, ↑ on the last;
 * in the menu ↑ ↓ (wrapping, skipping disabled) · Home · End · Enter/Space picks ·
 * Escape closes back to the toggle (and is marked handled, so a surrounding
 * `<baht-modal>` stays open) · Tab closes and moves on. A click outside closes.
 *
 * @fires baht-click - The main action was activated (click or its shortcut).
 * @fires baht-select - A menu item was picked. `detail: { value, item }`.
