/**
 * CX Chat support console.
 *
 * DESIGN NOTES (deliberate, please do not "tidy" these away)
 *
 * - ONE accent, injected from settings as --cx-accent. Channel identity is a
 *   2px left rule, not a colour wash, so three tags in a row stay legible
 *   instead of turning into confetti.
 * - Status is a solid 7px dot plus plain text. Never a pale tinted pill with
 *   darker text of the same hue: that is the most recognisable AI-design tell
 *   and it reads as decoration rather than information.
 * - Separation is whitespace first, hairlines second. Never a border AND a
 *   shadow on the same element.
 * - No pure white, no pure black. This is a screen an agent stares at all day.
 * - 4px rhythm throughout.
 *
 * PSYCHOLOGY
 * - An agent's real job is triage, so the list is optimised for scanning, not
 *   for reading: face, then name, then the one line of preview. A face is
 *   recognised faster than a name is read.
 * - The WhatsApp 24 hour window is shown as a live countdown, because it is a
 *   real deadline with a real consequence (after it, only a template can be
 *   sent). Honest urgency, never invented urgency.
 * - The composer is the only filled button on the screen. Everything else is a
 *   quiet text action, so the eye always lands on "reply".
 * - Destructive and irreversible actions are never adjacent to Send.
