 * for the mobile shell). The panel is 1420px wide wherever the screen has room
 * and gives up width, never size, where it has not.
 *
 * The left column is deliberately dark in both themes: it is a brand panel, not
 * a surface, so it does not read the surface tokens. Everything on the right
 * does. theme-lint-disable: the brand panel's colours are fixed by design.
