/**
 * KND // ACCESS GATE — V2 visual shell (auth.php?ui=v2, preview-gated).
 *
 * Self-contained: does not rely on auth.css, auth-split.css, Bootstrap or the global site CSS.
 * Everything is scoped to body.knd-auth-v2. Functional V1 hooks (ids, .knd-access-*, radios,
 * .auth-btn--loading, strength classes) are restyled here but keep the behaviour JS expects:
 *  - panels are shown/hidden by JS through inline style.display ('block' / 'flex' / 'none');
 *  - login/register tabs are toggled by the hidden radios via :checked ~ sibling selectors;
 *  - alerts start hidden and appear with .show (JS also sets inline display:block).
