/* ==========================================================================
   Landing page (pre-auth). Every selector is scoped under .landing, because
   this file loads on the same document as the studio and shares class names
   with it (.how-title, .brand, .input, .err all exist in both).

   One accent (periwinkle) in two steps: --pf-accent fills a surface and
   carries white text at 5.07:1; --pf-accent-ink is the only step allowed to
   BE text on the near-black ground, at 8.37:1. Nothing else is coloured.

   One radius rule, applied everywhere on this page:
     interactive (buttons, pills, inputs) -> 999px
     media, panels, cards                 -> var(--pf-r)
   There is no third value.

   Motion is transform/opacity only, and every scroll effect is a native
   scroll-driven animation (animation-timeline: view()), so this page carries
   no scroll listener. It is all switched off under prefers-reduced-motion at
   the bottom of the file.
