/* =============================================================================
   tenant-plus-signin.css   (v3 — premium redesign)
   -----------------------------------------------------------------------------
   Self-contained styles for _TenantPlusSignInModal.cshtml. The tp- prefix
   keeps this isolated from .ikh-modal-* (consumer sign-in) and .tp-onboard
   (LandlordRegister) styles.

   Design direction: refined editorial. A two-column shell — a deep brand
   panel on the left (gradient + drifting orbs + monogram + portfolio
   talking points) and a calm form panel on the right (serif display title,
   floating accent inputs, single decisive CTA shadow). Below 720px the
   brand panel collapses and the form panel gets a compact brand tag at
   the top, so mobile still feels intentional rather than truncated.

   Selector contract: every selector and data-attribute the existing
   tenant-plus-signin.js consumes is preserved (.tp-auth-modal-submit,
   .tp-auth-modal-spin, .is-loading, [data-tp-channel].is-active, etc.).
   Old class names that drove the v1 layout (.tp-auth-modal-band,
   .tp-auth-modal-band-beam, .tp-auth-modal-band-dot, .tp-auth-modal-head,
   .tp-auth-modal-hint) are intentionally dropped — the new markup no
   longer renders them, so leaving rules behind would only confuse a
   future reader.
