/* ==========================================================================
   login.css — futuristic BUILDER-workbench sign-in / invite-acceptance
   screens for the admin console. Loaded LAST, after css/console.css,
   css/kits.css and css/builder.css, so it inherits every kit token
   (--accent, --accent-2, --accent-strong, --glow-rgb, --bg, --panel,
   --border, --text, --text-muted, --font-mono, --radius-*, --shadow-*) and
   builder.css's own workbench tokens (--bw-graphite-0/1/2, --bw-hair,
   --bw-hair-dim, --bw-tick, --bw-grid-major/minor, --bw-radius). No colour
   is hard-coded here. Structural only — every id/name console.js reads
   (#signin-form, #si-email, #si-password, #si-totp, #si-error,
   #accept-form, #ac-name, #ac-password, #ac-password2, #accept-error,
   #accept-step-1/2/done, #accept-otpauth-uri, #accept-qr,
   #accept-totp-form, #ac-totp, #accept-totp-error) is untouched. The six
   digit boxes and the step indicator are purely decorative additions kept
   in sync with the real (now hidden) #si-totp / #ac-totp inputs by
   js/login-fx.js — console.js still reads those same ids' .value exactly
   as before. No external requests, no web fonts, no build step.
   Phone-first: correct at 375x812 and 1280x800, 44px targets, safe-area
   insets, AA contrast, visible focus rings, prefers-reduced-motion static.
