/* ═══════════════════════════════════════════════════════════════════════════
   ROUNDZ — LEGAL PAGES (terms.html · privacy.html)
   The landing's "floor of the exchange" terminal language, applied to a long
   document: one console rail, hairline dividers, mono section index, numbers
   and rules carried by type rather than by boxes.

   Shared by BOTH pages on purpose — they used to carry two identical copies of
   an inline <style> block, which is how they drifted out of the app's design in
   the first place. Tokens mirror :root in style.css; keep them in sync.

   No JS on these pages, by design (they must render if everything else fails).
   The TOC is therefore pure CSS: sticky rail on desktop, two-column index in
   the flow on phones.
