 * Full-width vertical region that paints the current surface. Panels always have zero block-spacing
 * (they butt up against each other vertically to create stacked page sections) but they do have
 * vertical `padding-block` — `xxlarge` by default, overridable via PaddingVariants (`.padding-large`,
 * `.padding-none`, etc.). Inline padding is fixed at `--space-normal`; if you want narrower content
 * inside a wide panel, compose a `<Block narrow>` (or `<Block wide>`) inside it.
