/* =========================================================================
 * auth.css — Apex & Chill account screens (sign in / register / reset)
 * -------------------------------------------------------------------------
 * Implements the split brand/form layout from the Apex & Chill design system
 * ("Hub" kit, Auth screens): a gradient-lit brand panel on the left, a single
 * 380px form column on the right.
 *
 * Same house rules as control-panel.css — system fonts only (no webfont can
 * load under the panel's CSP anyway), no blurs or backdrop-filters, one cheap
 * shadow. The design-system token NAMES are kept (--ac-*, --bg-*, --text-*) so
 * this file reads next to the design source, with the logo-native ramp the
 * desktop app already uses.
 * ========================================================================= */
