/* ============================================================================
   FILMPARTY_F5E_STEPPED_AUTH v2 — cinematic-dark brand theme.
   Direction distilled from 20+ leading auth pages (Netflix, Spotify, Disney+,
   Apple, Stripe, Linear, Vercel, Telegram, Revolut, Google): full-bleed dark
   backdrop, no glass/neon, typography-led hierarchy, ONE accent (the brand
   gradient) reserved for CTA / focus / progress, restrained 200–350ms motion.
   All inputs are ≥16px so iOS never focus-zooms (kept the page zoom-lock
   intact). RTL-first: back-links carry an outward (left) chevron.
