/* Contextual Help drawer (Layout/HelpDrawer.razor) + field highlight + HelpTip / HelpFieldsButton. Global because the drawer pushes
   the page body, sits above Radzen dialogs (non-modal: the user keeps working in the dialog) and pulses inputs outside the component.
   Ported from HarmonyCore (hc-*). Every colour is a Radzen / Px token (app.css redefines them under [data-theme="dark"], so the
   drawer follows ThemeToggle with no rules of its own); hex values appear only as var() fallbacks. */
