/* ============================================================================
   STARFALL — TERMS PAGE
   css/terms-page.css
   ----------------------------------------------------------------------------
   The terms document used to be the last section of the desk page: thirty
   clauses stacked under the CTA, reachable only by scrolling past everything
   else. It now has its own address, and this sheet is the only thing that is
   new — the clause typography itself still comes from terminal-pro.css §13,
   the tokens and buttons from terminal.css, so the legal text and the desk can
   never drift apart visually.

   What this layer adds is what a reference document needs and a landing page
   does not:
     · a sticky bar with a way back to the desk, and a reading-progress line
     · a hero that states the revision before you start reading
     · a contents rail that sticks, searches and marks the clause you are in
     · each clause as a panel, with a gold flash when you arrive from a link
     · a page-level "top" button, and a print stylesheet that drops the chrome
     · an ultrawide layout: past 1440px the shell widens and the width goes into
       the margin the clause numbers sit in, not into longer lines of legal text

   09. ULTRAWIDE
   --------------------------------------------------------------------------
   The desk's shell is 1320px, because a landing page that stretches to 3440px
   reads as a banner. A reference document is the other case: at 2560px a
   1320px column leaves two thirds of the screen empty, the rail stops looking
   like part of the page and the document starts to look like a PDF someone
   forgot to zoom. So the terms shell widens in two steps — and the width it
   gains is spent on the margin the clause numbers hang in, not on longer
   lines: every paragraph keeps a cap near 92 characters, which is the point
   past which an eye loses its place on the way back to the left edge.
