/* hey — TTY.
 *
 * A log stream, not a list of cards.
 *
 * Design rule, applied strictly: every pixel either carries information or is a
 * control. No film grain, no scanlines, no entrance animations, no drop
 * shadows, no decorative rules, no priority widget duplicating what the level
 * column already says. If it cannot be clicked and does not tell you something,
 * it is not here.
 *
 * The two remaining animations both encode state: the prompt cursor (input is
 * focused) and the health LED blink (backend is down).
