/* RZC storefront — the sign-in card (templates/storefront/auth.html), the
 * password and sign-out pages (templates/storefront/password.html,
 * signout.html) and the address book of the account page
 * (www/shop/account.html).
 *
 * Loaded by those two templates only, after rzc_storefront.css, whose --sf-*
 * tokens carry every colour: the tokens are redefined for the dark theme
 * there (prefers-color-scheme and html[data-theme="dark"]), so nothing here
 * names a colour of its own and both themes stay in step. Works down to a
 * 375px phone: one column, full-width controls, 16px gutters from the frame.
