/* ===========================================================================
   Auth — frontend/login.html (Sign In / Create Account)
   ---------------------------------------------------------------------------
   Built from `TradeMesh Login Package/TradeMesh Login.dc.html`. Deliberately
   NOT a fifth visual system: reuses landing.css's dark palette + falling-
   masonry wallpaper wholesale (link base.css + landing.css + landing.js on
   login.html, same as landing/index.html) — the login reference is where
   that background mechanic originally came from, and landing already
   carries the "match dashboard.html's colors" correction, so reusing it
   here keeps the whole marketing→auth→app journey visually continuous.
   This file only adds the card/form-specific pieces landing.css doesn't
   have. Scoped under body.landing (same body class as landing.html).
