/* Daily Life Doc: the one chat (round 6; round 9, zone U; round 10, zone P: docs/build/r10/PLAN.md section 3.2, the
   page "One chat", Part 1). Three parts, drawn by the files under js/req/ and js/convo/:
     1. the rows at the top of Today: one soft tint, the words cut after two lines ("App" before the app's own
        question), the answer buttons, the call rows; Clear behind a row (a swipe) and the ✕ on a computer; the
        character's host under the rows (req-row.js, req-top.js, req-swipe.js, js/today/today-char.js)
     2. the page `chat` and Patient's view (req-chat*.js, convo-msg.js, convo-keyed.js, convo-view.js): the frame with
        its columns, the day dividers, "Reading…", "Not sent · Try again", "App", the Call me card (css/chat.css)
     3. photos and files inside a message (js/msg/msg-files.js)
   Tokens and the type scale of base.css only. Pink (--care, --tint-team) is only what the care team alone sees; the
   patient reads white and ink. */
