/*
 * HRIS login — glass card over a particle field.
 *
 * Design copied from the legacy Yii2 sign-in page:
 *   navy #1d243d backdrop · translucent card · 10px blue top rule + 10px gold
 *   bottom rule · dark slate inputs · light-blue pill button that turns purple
 *   on hover.
 *
 * The legacy sheet positioned the button and error bar absolutely inside a
 * fixed 400x400 box. That is reproduced here as normal flow instead — Filament
 * injects its own form markup and validation nodes, and absolute offsets would
 * break the moment an error message appears.
 *
 * Loaded only on the login route (render hook scoped to the Login page), and
 * everything is namespaced under .fi-simple-layout / .hris-glass-card so it
 * cannot leak into the authenticated panel.
