/* =====================================================================
   Thread · the style
   The forum and community: Space Grotesk for headlines, Inter for
   reading, Fira Code for counts and code, on paper with ink, one
   ultramarine, mint for what's solved and a red flag only for reports.
   Signature pieces: the thread list (.threads: votes, tags, solved,
   sorting), the discussion (.discussion: nested replies hanging off a
   visible thread line, an accepted answer, collapsing, and a report on
   every post), the report (dialog.report: reasons, the 7-day defamation
   path) and the composer (.composer: similar threads as you type, a
   toolbar and a live preview).
   Motion: html.calm stills everything (footer switch, remembered as
   "site-motion"; default from prefers-reduced-motion).
