/* Product /chat only — Times New Roman FACE.
   Marketing pages keep Instrument Serif / Inter in shared/styles.css
   and shared/site.css. Do not import this sheet from those surfaces.
   fonts.css is generated; this file is the chat-only face override.

   Face only. Do not set body font-size / line-height / letter-spacing,
   and do not reset .memo-prose / .msg-user .msg-body / .composer textarea
   measure or leading. The page-local desk (66ch / 15px / 1.65 and
   16px / 1.5 / min-height 72px) must win. Tokens already set the face. */
