 * mlp-sidebar styles. Import after platform.css, same convention as mlp-forms — reuses its
 * tokens (--c-*, --s-*, --shadow, --radius-sm). This is the panel *mechanism* only: width,
 * background, and the responsive collapse-into-a-drawer behavior. Content sections inside it
 * (brand, nav, account — or whatever a second sidebar holds) are the consuming page's own CSS.
 * The dropdown-menu mechanism this package's own account/app-switcher menus use lives in
 * mlp-dropdown-menu.css now, not here — see that package's README for why it moved out.
