   AMS — login-v3.css  (2026-10-15)  "Live Studio" sign-in page
   Fixed look (no user theme). Segoe UI. Responsive:
     • ≥1600px wide  — roomier, capped widths
     • 981–1279px    — tighter columns, floating chip hidden
     • ≤980px        — single column: form only, logo on top
     • short screens — showcase compacts (≤820px / ≤700px tall)
