/* Dialog shell – a native <dialog> that fills the screen, dims the page and animates its panel in and out.
   .dlg          the <dialog>; scrolls when the panel is taller than the screen
   .dlg__panel   the panel; its width comes from --dlg-w, the content component styles the inside
   .dlg__close   round close button in the panel's top right corner
   dialog.js adds .is-open after showModal() and removes it before close(), so both directions animate.
   On phones the panel fills the screen and slides up. */
