/* croon.tv (#693, 2026-09-24): one screen.
   The Midjourney still (K, audio equipment) sits full width and is never enlarged
   or cropped; a dark veil over it keeps the headline readable. Beside the headline
   the launch video plays and, when it ends, the card turns over to the on-device
   recording, then back again. Orange is only for the words that turn in the
   headline. Mock and its history: docs/design/20260923-i693-croontv-hero.md. */
