/* =============================================================================
 * CyphCard — iOS design layer
 * -----------------------------------------------------------------------------
 * Loaded LAST on every page, after the page's own stylesheets.
 *
 *   1. System tokens      --ios-*  Apple-style semantic colours and glass
 *                                   materials for light and dark.
 *   2. Legacy tokens      --cc-*   Only defined in light mode. The legacy CSS
 *                                   was rewritten to var(--cc-..., original),
 *                                   so dark mode renders the original colours.
 *   3. Foundations        typography, tap feedback, focus, safe areas.
 *   4. Materials          Liquid-glass surfaces for the app's panels.
 *   5. Controls           buttons, fields, tables, badges.
 *   6. Appearance UI      floating theme button and segmented control.
 *   7. Responsive         phone / tablet / desktop adjustments.
 *
 * Specificity: rules are prefixed with `html` (or :root) so they win over the
 * page stylesheets without !important. `:where()` keeps a rule at zero
 * specificity where a page must still be able to override it.
