/* ==========================================================================
   Lightning Payroll — authentication forms (login / forgotten / password /
   update credit card). Self-contained, namespaced under .lp-auth so it never
   touches the rest of the storefront. Built on the existing Rainbow theme
   tokens, with a single light-mode override of component-scoped variables so
   every rule below adapts to both dark and active-light-mode automatically.
   Loaded after style.min.css (see common/header.tpl).
