   QOTE · PRODUCTION CSS · v1 (editorial)
   Forest & clay palette, Playfair Display + Inter + IBM Plex Mono, editorial.
   Mobile-first. Design tokens via CSS variables.

   2026-06-07 — Reverted the "Bold Modern v2" overhaul (rounded pills,
   gradient text, glassy blur, depth shadows, ambient washes). That direction
   fought the sharp editorial homepage. This system is flat, 0-radius, mono-
   labelled and paper-toned to match the Qote homepage 1:1. Only the tasteful
   scroll-reveal (fade-up) is kept from v2.
