/* ============================================================
   ADR Tempmail — UI v2 "paper & ink"
   Design language ported from tryclico.com (same as dl.adrnode.com,
   gateway.adrnode.com, predict.adrnode.com):
     cream paper on lavender, graph-paper substrate, 2px black outlines,
     zero-blur offset shadows, Instrument Serif display /
     Instrument Sans UI / JetBrains Mono for addresses & timestamps.

   Every class name is preserved — web/app.js drives .message-item,
   .message-avatar, .empty-state, .email-render, .domain-select, etc.
   and was NOT touched.
