- AuthShell: dark two-column auth layout (brand/value panel with CSS-only
waveform motif + proof points + Bland-style enterprise CTA block on the
left, zinc-900 form card on the right; single-column on mobile).
- AuthEnterpriseCTA: "Talk to our team" → dograh.com/contact?intent=enterprise.
- stack-theme: dark StackTheme token overrides synced to globals.css.
- page.tsx: wrap StackHandler (non-fullPage) in AuthShell + StackTheme;
local-auth fallback preserved inside the shell. BackButton slimmed for the card.
- Dark locked as default: <html className="dark">, next-themes ThemeProvider
(defaultTheme="dark", enableSystem=false); inline no-FOUC script defaults dark.
