/*
 * Shared styles for the Greenhouse web UI (Datasight Skleník).
 * Plain CSS, no build step. Colors are CSS custom properties so light/dark
 * mode (via prefers-color-scheme) only needs to redefine the tokens below.
 *
 * Class reference (kept stable across pages — Task 4 / history page reuses these):
 *   Layout:   .container, .header-inner, .nav, .grid-2, .toolbar, .divider
 *   Cards:    .card, .card-title, .value-large, .motor-tile
 *   Buttons:  .btn, .btn-primary, .btn-danger, .btn-secondary, .btn-outline, .btn-sm, .btn-block
 *   Forms:    .label, .input, .form-row, .form-group, .checkbox-label, .alert, .alert-error, .alert-info, .auth-links
 *   Status:   .status-banner (+ .status-ok/.status-error/.status-neutral/.status-ws-on/.status-ws-off)
 *   Badges:   .badge (+ .badge-success/.badge-info/.badge-muted/.badge-danger/.badge-output/.badge-input)
 *   Switch:   .switch (wraps a checkbox input + .switch-track)
 *   Table:    .table
 *   Toasts:   #toast-container, .toast (+ .toast-success/.toast-error), created lazily by GH.toast()
 *   Console:  .console-box, .console-grid, .console-card, .console-label, .console-value,
 *             .console-section-title, .pin-row, .state-badge
