/*
 * The one visual foundation behind the signed-in product: the sign-in pages,
 * the merchant dashboard and the operator console all load this first.
 *
 * It holds what makes the three read as one product (palette, type, radii,
 * depth and the handful of element defaults every page needs) and nothing
 * about layout. Each area's own sheet (auth.css, dashboard.css, platform.css)
 * builds its components from these tokens and never re-declares a colour, so
 * a change here lands in all three at once. Before this file each of them
 * carried its own copy of the palette, and the copies had drifted: the
 * dashboard was Tailwind's zinc grey while the sign-in page and the landing
 * page were the brand's blue-black.
 *
 * The rules, stated once:
 *
 *   Colour   A blue-black ground taken from the landing page, neutrals with a
 *            faint cool bias so they sit with the violet instead of against
 *            it, and one accent: the logo's violet. The accent marks what you
 *            can act on and where you are (primary buttons, the current page,
 *            links, focus). It is never a gradient, a glow or decoration.
 *            good / warn / bad / info are status colours, kept apart from it.
 *   Shape    Controls (buttons, fields, menus) --radius-sm, 8px. Containers
 *            (panels, tables, dialogs) --radius, 12px. Status tags
 *            --radius-tag, 6px: squared, so a status never looks like a
 *            button. Full round only for avatars and the language switch.
 *   Type     The platform's own UI face (Segoe UI Variable on Windows, SF on
 *            a Mac): nothing to download, and it is what the operating system
 *            already renders forms in. Sentence case everywhere; figures are
 *            tabular wherever they line up.
 *   Depth    A border, not a shadow. Shadows only on what floats over the
 *            page: menus, dialogs, toasts, the mobile drawer.
 *
 * Themes. The dashboard, the console and the sign-in pages are light, like
 * the landing page: their shells stamp data-theme="light" whatever the theme
 * cookie says (the sign-in pages in _auth_layout.html). Dark stays the base
 * block below; the unstamped "system" state still follows the media query.
