    • 2:32 - Style the select button
    • Apply `appearance: base-select` to opt into the new styling model, then customize the button with familiar CSS — fonts, background, border, and padding. Use the new `::picker-icon` pseudo-element to swap the dropdown arrow, and the `:open` pseudo-class to change colors when the menu is showing.

    • Style the menu itself by applying `appearance: base-select` to the `::picker(select)` pseudo-element. Adjust spacing, borders, and box-shadow, emphasize the active option with the `:checked` pseudo-class, and replace the default checkmark using `::checkmark`.

    • 5:00 - Go beyond text options
    • Place rich content like SVG icons, images, or labels directly inside
