Subject: [PATCH] Update Tabs example to use lambda event handlers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace verbose boilerplate (set_tab_0, set_tab_1, etc.) with clean
lambda syntax using the new feature.

Before (18 lines of boilerplate):
  def set_tab_0(): tab_index = 0
  def set_tab_1(): tab_index = 1
  def set_tab_2(): tab_index = 2
  def set_setting_0(): setting_tab = 0
  def set_setting_1(): setting_tab = 1
  def set_setting_2(): setting_tab = 2

After (2 lines):
  def set_tab(value): tab_index = value
  def set_setting(value): setting_tab = value

Usage:
  onclick=lambda: set_tab(0)
  onclick=lambda: set_setting(1)

Generated WASM: 8810 bytes (smaller than before!)
Lambda functions: 36 total (12 per component × 2 components)
