  Render a 150 px QR code encoding an LVGL URL with custom dark and light colors.
</LvglExampleBrief>

A QR code widget is centered on the active screen and sized to 150 px.
`lv_qrcode_set_dark_color` and `lv_qrcode_set_light_color` use
darkened and lightened entries from `LV_PALETTE_BLUE` and
`LV_PALETTE_LIGHT_BLUE`, `lv_qrcode_update` encodes `https://lvgl.io`,
and a matching 5 px border is applied via local style properties.
