/* vault-shell.css — Session™ Vault auth/onboarding shell styles.
 *
 * 2026-05-11 — the design handoff referenced this file from onboarding.html,
 * tiers.html, forgot-password.html, reset-password.html, landing-apex.html,
 * and signup.html.bak but the file itself was never written. Without it the
 * 5 surfaces fell back to inline styles + session-brand.css, which left the
 * outer card shell, halo, gradient CTA, and progress dots unstyled. This is
 * the canonical implementation of those primitives so all five pages render
 * the way the designer intended.
 *
 * Scope: shared shell layout + animated halo border + gradient submit button +
 * status pill + footer. Page-specific styles stay inline in each HTML so
 * variants don't leak.
