/* ---- Pre-login surface: shared primitives ---------------------------------
   Landing, log in, sign up, "check your email" and the reset pages are one
   surface. This file holds what all of them use — band rhythm, the eyebrow
   type treatment, the buttons, the sign-in card and the footer. Landing-only
   sections live in `landing.css`.

   Tokens only: every colour, size and space here resolves through the custom
   properties in `base.css`, so the M2 per-tenant accent keeps working. */
