/*
 *  Auth pages — shared shell styles (sign-in / sign-up / verify-otp /
 *  forgot-* / reset-* / account-locked / recovery-success).
 *
 *  Everything is scoped under `.auth-shell` so the auth pages can use the
 *  marketing-brand `--page-*` / `--hero-*` token system without polluting
 *  the dashboard's design-tokens.css.
 *
 *  Companion of /Users/gateri/Downloads/apps-web/*.html — preserves the
 *  HTML class names (.topbar, .signin, .signin__left, .terminal, .otp-grid,
 *  etc.) so JSX from those designs lands here unchanged.
 *
 *  Fonts (.logo__text / .signin__left-title / .signin__title) are mapped to
 *  --font-logo, which is wired to PassionSansPD in design-tokens.css.
 *  --font-body falls back to the portal's body stack.
